My DD is 18mths and she like to walk on her toes.

i havent thought of it as much as a problem, just though she like to be taller.

She doesnt do it all the time and i see alot of children who do it.

If you are at all concerned have a word with you GP but I dont think is such a big deal. my DD also like to crawl still every now and then and she has been walking since 9 mths.

Kids just like to do different things and experiment. They could just like the feeling of walking on there toes.
