ADAPTATION FOR BEING CARRIED
Anatomic examinations by Prof. Dr. med. Buschelberger (Dresden) showed that the head of the thighbone in a newborn is ideally orientated towards the hip socket - and thus fills it out evenly-when the legs are pulled up to approx. 100 degrees and spread approx. 40 degrees at the same time. When infants are picked up they take up this posture spontaneously and therefore it has to co-operate when their anatomic conditions.
As well, the rounded back (kyphosis) doesn't stretch out immediately after birth. On the contrary, the well-know double-S-form of the spine is developing fully at the beginning of self-supported walking.
These anatomic conditions, together with the palmer grasp reflex of the first days in life, suggest that infants are especially adapted to being carried on our body.
Thus, it is possible to make a statement about the ideal carrying position: with wide-spread, flexed legs, slightly rounded back, and orientated towards the carrying adult
