Ten Things Everyone Should Know About Babies

Ignorance about babies is undermining society

1. Babies are social mammals with social mammalian needs. Social mammals emerged more than 30 million years ago with intensive parenting (a developmental nest or niche). This is one of the many (extra-genetic) things that evolved other than genes. This developmental nest is required for an individual to develop properly. Intensive parenting practices for babies include years of breastfeeding to develop brain and body systems, nearly constant touch and physical presence of caregivers, responsiveness to needs preventing distress, free play with multi-aged playmates, and soothing perinatal experiences. Each of these has significant effects on physical health.

2. Human babies are born "half-baked" and require an external womb. Humans are born way early compared to other animals: 9 months early in terms of mobility and 18 months early in terms of bone development and foraging capacities. Full-term babies have 25% of adult brain volume and most of it grows in the first 5 years. Thus, the human nest for its young evolved to be even more intense than for other social mammals because of the underdeveloped newborn, lasting for 3-5 years. Humans also added to the list of expected care a village of positive social support for both mother and baby. Actually, human brain development lasts into the third decade of life, suggesting that social support and mentoring continue at least that long.

3. If adults mess up on the post-birth “baking,” longterm problems can result. Each of the caregiving practices mentioned above has longterm effects on the physical health but also social health of the individual. For example, distressing babies regularly or intensively (by not giving them what they need) undermines self-regulatory systems. This is common knowledge in other cultures and was so in our past. In Spanish, there is a term used for adolescents and adults who misbehave: malcriado (misraised).
