my newborn baby (11 days) always keeps his legs folding. but occasionally stretch, when he feels warm. is it ok?

ya it's normal ... just do mild streches by applying oil before bath... massaging helps your baby to attain Normal ..

Completely normal. Babies in the womb have very little space and hence they keep their legs folded. This is why post birth also they keep their legs folded.

gentle massage bya mother is helpful for her body and skin , don't go for amma's
