hi doctor. my daughter turned 2 years on 1 may and still she isn't walking independently . she stands on her own but when we ask her to walk she sits on her knees. I am very concerned about it . I also checked with her paediatrician, he checked and there is no issue with her legs .it's just she doesn't want to walk. how can I make her walk independently. is there any activity or exercise that can help her walk?
