biological nurturing

Also: biological nurturing model, Colson method

A breastfeeding approach, described by Colson, in which the mother reclines and the baby lies on her body and uses newborn reflexes to find the breast.

In plain words

Biological nurturing is an approach to breastfeeding described by the researcher Suzanne Colson. The mother leans back in a semi-reclined position, and the baby lies face down on her chest, often . The approach relies on . Babies are born with automatic movements, such as rooting, stepping, and grasping, that can help them reach and attach to the breast. In this position, gravity helps hold the baby's chin toward the breast. Supporters say the position lets babies feed with less help from adults. Some mothers find it useful. It is one of several positions taught in breastfeeding care, and it is not required for successful feeding. Research on its effects is limited, so it is best seen as one method some families try.

The deeper version

Colson's biological nurturing model describes about 20 primitive neonatal reflexes that, with the mother semi-reclined and the infant prone on her body, become supportive of feeding rather than disruptive. Gravity holds the infant's chin toward the breast, and the infant's own hand and mouth movements guide . The model was set out by Colson, Meek, and Hawdon (Early Human Development, 2008) in work on optimal positions for releasing primitive reflexes. Evidence for better latch, duration, or nipple outcomes compared with standard positioning is limited, mostly from small observational or pilot studies. Reflex responses vary from one infant to another, which limits how far the model can predict feeding. The approach is included in some lactation training as one positioning option.
