“When Phoebe’s little legs are tucked under her body, I see how she was able to fit into the tiny space of the womb. At first I was concerned because I didn’t know why her legs were positioned like that.”
Babies born at gestational term have a tightness to their bodies called physiological flexion. Space was limited in the final trimester and the baby assumed the most compact position with arms and legs held close to her core. Physiological flexion provides some passive stability for the newborn baby to use for function. Practice will provide an opportunity to decrease muscle tightness through active movement. In turn, active movement provides sensory input and postural control. Development happens gradually, month by month with one skill building upon another. The posts in the milestones category describe the maturation of babies in the first year of life as they begin tightly flexed and learn to roll, sit, cruise and stand.
