Neurological Developpment in Humans

One day my general practitioner told me that carried children are neurologically different than children who are not carried which means they are molecularly different. I was fascinated so I started to read everything I could find about carrying.

I have noted some of the things I have read about carrying with references when possible.

  1. Anthropologists are unanamous; Baby carryers are the first tools ever invented by man. Before the hammer, fire or wheel. As much as breastfeeding, carrying has assured the survival of our species. (The Prehistory of Sex Timothy Taylor. Bantam Books.)
  2. Humans are born 9 months premature. The average lifespan of most mamals on the planet is a lot shorter than that of humans. Rhodents live for less than 10 years, dogs live about 10 years, Horses live about 25-30 years. Humans live to about 85 years so relatively should be born after about 18 months gestation. The oversized brain makes us impossible to get through the birth canal after about 9 months although we are unfinished. Like the kangaroo we are born in a foetal stage. For optimum neurological and biological development our biological need is to latch on to our mother’s breast in a pocket for about 9 more months. Other mamals are ready to consume other foods than their mother’s milk and walk within several hours of weeks of birth. (Touching, the Human Significance of the Skin : Montagu, plus Boris Cyrulnik.)
  3. As soon as the umbilical cord is cut human babies need almost continual contact to ensure primitive confidance. (the Emotional Life of the toddler : Aleiciea Fleiberman. M.D. and Touching, the Human Significance of the Skin : Montagu)
  4. Humans are born with primitive needs which are really an archaic fear of being left alone. (Touching, the Human Significance of the Skin : Montagu)
  5. The earlier the mother infant separation, the greater the anxiety is as if imprinted in humans. A kind of background anxiety sets in. (Touching, the Human Significance of the Skin : Montagu)
  6. Babys need movement, contact and a human voice to develop primitive confidence. (Touching, the Human Significance of the Skin : Montagu)
  7. A study on 49 illiterate societies conclude that where carrying, contact and touching occurs in great frequency and high levels, the levels of aggression are the lowest. Comparatively, in the societies where carrying, contact and touching is infrequent and uncommon, levels of aggression are high and common. (Prescott & Wallace, NICHD & University of California Medical school. U.S.A. ref: Good Nights. Dr. J. Gordon.)
  8. With primitive confidence a baby’s energy can be used to develop the brain. Optimal neurological connections are made. (Touching, the Human Significance of the Skin : Montagu)
  9. When baby monkeys were separated from their mothers, the cortisole level was mesured and found to be extremely high. The babies were repeatedly left alone, and allowed to cry for their mothers until they fell asleep. When the babies stopped crying for their mothers their cortisole levels were measured again and found to be just as high as when they had cried for their mothers, even after 80 separations. (Good Nights: J. Gordon. Study: Coe et al 1985)
  10. High levels of cortisole weaken the immune system. Psychiatric research conclude that adults and teenagers susceptible to depression, antisocial behaviour, alcohol, drug abuse and repetetive illnesses were babies that were left to cry alone. (David Servan-Schreiber PHD, Pittsburgh School of Medecine.) In separate studies, patients who had been left alone to cry as babies were found to be more susceptible to mental illness and have more difficulty recouperating after a stressful event. (Michael L. Commons PHD Harvard University, Lecturer in Psychiatry.) Read: Good Nights, Dr. Jay Gordon p. 97.
  11. The earlier the skin stimulation; stroking, carrying, the higher the immunity levels. What worries a baby is silence, lack of movement, and solitude. This stress is otherwise known as an archaic fear of being left alone to die.
    Birch, Lorraine L Roth, Jay S Rosenblath. Harry Harlow, M.K. Harlow, E.W. Hansen. Study; The maternal affecctional system of rhesus monkeys. New York, Wiley 1963. (Touching, the Human Significance of the Skin : Montagu)
  12. In Bogota, Columbia, the premature born mortality rate was above 70%. In part because of unreliable electricity but mostly because mothers abandonned their premies. With the introduction of Kangaroo Care, the rate dropped to 30%. In the U.S. with incubator care alone the rate stayed at 30%. Kangaroo Care is today practiced on a 24/24 skin to skin basis. Parents leave the maternities with their premies in continuous Kangaroo Care only days after the birth. Today the incubators are used to heat laundry. (“Kangaroo Care”: Susan Ludlow)
  13. A child who has been carried will have better digestion, fewer skin problems, fewer colics, greater memorisation and learning capacities, better frustration tolerance, better integration capacities, more creativity. On average children carried walk earlier. (Touching, the Human Significance of the Skin : Montagu)
  14. A carried child will have a higher I.Q. greater immunities, better intestinal developpment, and they sleep better. They will have better vision, sense of smell, balance, muscle tone and infecions are rarer. (Touching, the Human Significance of the Skin : Montagu.)
  15. One study showed a 48% reduction in daytime crying and a 51% reduction in nighttime crying. (Paediatrics 1996)
  16. Children who were little touched, little held, have brains that can be up to 30% smaller than other children their age. (Touching, the Human Significance of the Skin : Montagu)
  17. Carried premature babies have deeper sleeps, gain wieght faster, infections are rarer, cry less and their energy is better conserved. The interrupted gestation period can be prolonged when being carried skin to skin. (“Kangaroo Care”: Susan Ludlow)
  18. Psychomotor developpment is more rapid and harmonious in carried babies. (Touching, the Human Significance of the Skin)
  19. After 8 weeks of gestation, the foetus has skin and can feel pression throught the uterus wall. (Touching, the Human Significance of the Skin. Montagu.)
  20. At 8 months of gestion the foetus is entirely envelopped in the uterus, every centimetre of its skin is being touched and massaged by the utuerus wall. This is known as "Flesh Nirvana". (Touching, the Human Significance of the Skin)
  21. Until about 9 months of life extra-uterine, a human baby believes itself to be a physical part of its mother. (Touching, the Human Significance of the Skin.)
  22. Hormonal secretions in babies change depending on the expression of their mother. (Dr. Janov: The Biology of Love).
  23. Average crying in carrying socities is 5 minutes a day. Average crying in N.A. is 2 hours per day. (The Family Bed; Tine Thevanin)
  24. Separation at birth is an occidental phenomenum as is prolonged crying. (The Family Bed; Tine Thevanin)
  25. Babies in Uganda creep on their bellies on average at the age of 5-7 weeks and can pick up an object while running at the age of 5-7 months. A N. A. child creeps at between 7-8 months and can pick up an object while running between 15 and 18 months. Marcelle Geber. (maternage.free.fr/la_peau-au-commencement.htm)
  26. Hip dislocation is principally an occidental phenomenum most common in intense stroller use societies. It is also a result of long hours spent lying on the back or front. (maternage.free.fr/portage_hanches.htm)
  27. A carried baby or child can participate in family life and live every new event in total security.
    (E Bonnet, E Kirkilionis, perinatalite.chez.tiscali.fr/portage.htm)
  28. Strollers and Perambulaters were commercialised in the middle of the 19th century and were used to relieve servants of back pain. (Three in a Bed. Deborah Jackson)
  29. Separation at birth is an occidental phenomenum as is prolonged crying. (The Family Bed; Tine Thevanin)
  30. In Baltimore in 1938 infant mortality rate was 35% until the prenatal education programme included carrying. The rate went down to 10%. (Touching, the Human Significance of the Skin. Montagu.)
  31. In the early 1900s in the U.S. orphanges lost babies at the rate of 60%- 100% at the height of the “Behaviourist mouvement”. When a doctor implemented a 3 times a day “holding” programme, the mortality rate went down to 10%. (Touching, the Human Significance of the Skin).
  32. Correct carrying is a method for prevention of hip problems and also used as treatment. In fact the Paediatric plaster casts were developped by paediatricians when they realised that hip displacement is almost inexistant in carrying societies. (maternage.free.fr/portage_hanches.htm. Plus; E Bonnet Paediatrician and E Kirkilionis)
  33. Experiences by Dr. Harry Harlow who had the hypothesis that babies want to cling to their mothers only to have 24/24 access to milk discovered; When separating baby monkeys from their mothers and leaving them in a cage with a "surrogate" mother consisting of two wire grids. One grid was covered with soft fur and had a lightbulb behind it, supplying heat. The second "surrogate" mother in the cage was a wire grid supplying milk 24/24. The baby monkeys clung to the warmed cloth covered "surrogate" mother for the vast majority of time in the cage, seldomly straying from it. In some cases, the baby monkeys went for upto 17 hours without feeding in order to cling to the heated grid. Other findings from this study show that the earlier the babies were separated from their mothers the more difficult re-integration in their social group was. Most monkeys never fully re-integrated. The few female monkeys that did manage to copulate abandoned their babies at birth or soon after. (Touching, the Human Significance of the Skin: Harlow Experiments)
  34. Franz II of Germany carried out experiments of his own. He wanted to know what language a child would speak if never spoken to. He bought babies and entrusted their care to nurses who were instructed to never speak to their tiny charges or touch them in an agreeable manner. We will never know the answer to the question becaus all the babies in this experiment died. (Touching, the Human Significance of the Skin.)
  35. Why is separation at birth a common practice in occidental society ? We can thank an american Dr. who in the 1940s, at the height of the behaviourist movement, decided that mothers would be separated from their babies at birth and allowed to hold them in their arms and attempt to breastfeed them for a 20- 30 minute period once every 4 hours. In between these brief moments, the babies were allowed to cry their desperation in vast nurseries. (Touching, the Human Significance of the Skin. )
    Post natale depression was rampant and psychology is a vast inudustry today. (authour's note)
  36. SIDS is almost inexistant in societies that share sleep. (Michel Odent). Between 75% and 90% of victims of SIDS are isolated sleepers at night. (Authour’s note)
  37. Why are such impractical contraptions so popular today despite such active lifestyles ? All new parents want "the best" for their children but are rarely faced with information or studies. Parents are left with is advertising. The goal of advertising is to convince the potential client that the best sacrifice they can possibly make for their baby is buying whatever equipment they are paid to sell. Innocent parents with apparently no choice become customers and their babies are the loosers in the trade. Stress becomes an accepted aspect of daily life. "the affliction of the century". (Author’s note.)
  38. Advising a parent to allow their baby to cry alone, destroys any confidence a parent may have been able to develop. Carrying gives a parent the ability to console and soothe a baby even if they can't rectify or heal a problem. Carrying reinforces parental confidance and family bonding. Parents must learn early to know the difference between advice and information in order to build confidence.
    (Rita Messmer Studer. maternage.free.fr/portons_nos_bebes.htm)
  39. One of the founders of destructive advice ?
    In 1892 in the United States, a nursing school educator published a textbook emphasised that "a baby should never be rocked nor hushed on a nurse's neck". This advice was dispatched accordingly to new mothers as well.
    In another vastly popular textbook written by a man who had neither given birth nor breastfed a single baby, a paediatrician, Dr. Luther Emmett Holt, wrote in spite of the glaring facts of life "To induce sleep, rocking and all other habits of this sort are useless and may be harmful. I have known of an instance where the habit of rocking during sleep was continued until the child was two years old; the moment the rocking stopped the infant would awake." In 1894 Holt published another popular guide called "The Care and Feeding of Children: A Catechism for the Use of Mothers and Children's Nurses". Regarding the question of rocking Holt replied in his guide; "Rocking is by no means necessary. It is a habit easily acquired, but hard to break and a very useless and sometimes injurious one." In 1916 Holt revised his guide, adding; "A crib should be one that does not rock, in order that the unnecessary and vicious practice may not be carried on."
    The use of the word "vicious" had obvious repercussions on many generations of mothers and babies to follow. Dr Holt encouraged scheduled breast feeding and the use of the bottle. By 1935 Dr Holt's book was in its 15th edition. (P 148 - 149 Touching, the Human Significance of the Skin).
  40. Nasa researchers among others conclude that one of the causes of osteoporosis is “the lack of weight bearing on long bones”. (afpafitness.com/articles/milkdoc.htm)
  41. Parental bonding is made easier, especially following a medicalised or traumatic birth or in the case of separation. (“Kangaroo Care”; Susan Ludlow.)
  42. In a study on plastic baby carriers vs fabric baby carriers mothers were distributed carriers at birth. When their babies were 13 months old the mother child attachment was tested and found to be solid in 41% of the plastic seat carried babies and 83% of the fabric carried babies. (The Lancet 1987)
  43. Observers note that no other mammal on the planet takes care of its young during the day and not at night.
  44. Transport in cloth slings is the least costly mode of transport, the most practical, answers to parent and child's need for contact and frequent feeding while on the go and is the only method that reduces medical costs.
  45. The more solid the mother/child bond, the more rapidly the child is ready to create relationships with other people. (Touching, the Human Significance of the Skin)
    Carrying reinforces parental confidence. Even when an affliction is unidendifiable, carrying provides the parents with a means to console, comfort and sooth a child. (Kangaroo Care : Susand Ludlow)
  46. To impose isolated sleeping on a baby, with no possibility of hearing the breathing of his parents unable to smell his mothers scent is a form of violence. This violence is often defended in the name of an adult desire for “peace”.
    Early imposed mother/ infant separation does not help a child become independant however does increase fear of abandonnement and reinforce co-dependance. Independance is built on feelings of security. (Au coeur des émotions de l’enfant. Isabelle Filliozat).
  47. Oedipus. Parents are often warned that sleeping with their babies or children is morally unhealthy, citing for proof, the story of Oedipus. The point of the Oedipus story that is so clearly overlooked is that Oedipus was abandonned at birth by his mother. He was unable to bond with his mother. Thus an incestuous relationship in adulthood was possible. For more information on incest read; Boris Cyrulnik.
