hi.. my baby is 1 year and still not able to walk.. she is not standing even.. when we try to do so.. she is smiling and do crawling always.. she is active but not keeping her foot on the floor.. she stands and walks with the support only.. if she stands means she always looks for support to move her foot.. otherwise she crawls n moves.. if we kept her in walker she simply sits.. as it became habituated since 6 months.. she is very active and happy but not able to walk.. someone suggest me what to do..
