What is the physiological position ?

This posture maintains Baby’s spine in a curve and centers his body, his limbs close together, knees and elbows bent – this position gives him a basic sense of security.

A correct posture for a newborn is what logically follows his life in utero. During his first 18 months, muscle tone and development will allow him to gradually straighten his back and stand.

This position also allows Baby to feel the outlines of his body, which is essential to his psychomotor development and will avoid incomfortable situations when he lacks support: arms and legs spread, head falling backwards, hands flopping around…

Keeping Baby wrapped in a respectful, stimulating of psychomotor development posture is an important aspect of babywearing. More info on the interests of a good position when wrapping.

 

 

A quick description of the physiological position :

 

  • Limbs are bent and close together near Baby’s center of gravity
  • Knees are lined up with the navel
  • Pelvis is tilted forward
  • Spine is in a curve
  • Head is lined with spine
  • Head doesn’t fall forward nor backward, and doesn’t loll sideways
  • Ankles aren’t turned away from the tibias and femurs



  • Before Baby reaches 3-4 months, his knees open only as wide as his pelvis
  • After 3-4 months (when Baby can grab his feet on his own) the space between the knees can be wider, Baby can straddle the wrapper.
