My little is 19 months, has been walking for 11/12 months.. recently she has been tippy toe walking, swaying her hips, walking around like…. Crouched down if that makes sense. And always always always has to have her legs up when laying down or sitting on furniture (not on the floor) the legs needing to be up has been since she was probably 2 months… the dr said her legs are fine. But…. Lately with the crouching I feel like something is wrong… anyone else experience anything like this? Is this normal?
