Does anyone have any advice what I should do with DD2 who is 27months and still walks on tip toes? I tell her sometimes to walk with flat feet, she understands me but it only lasts a few steps. Can this be a sign of something else, is it a problem, where do I start to correct this? My DS who has just started walking he is 14months but he walks on flat feet so now I'm really noticing her walking! DD1 also walked a bit on tip toes but had out grown it well and truly by 2.
