DS is 3.5yrs, and has loved walking on his tiptoes eversince he learnt to walk. He stands with heels down, and occassionally walks like this too (i.e. normally!)- but mainly runs or dances about on tiptoes. I'm sure I read somewhere this is fairly common and not to be concerned until they are 5 or so, but I have a friend who was a serious gymnast and explained that his hamstrings will be tighter from all his tiptoe-ing and perhaps we should do "more" to get him to walk properly with the normal foot action. Now I'm worried.
Advice please!!
(PS. he is very active, constantly running, jumping,climbing and I'd say his gross motor development is very good generally, excellent balance etc., can pedal a bike etc.)
