I don't have any personal experience but heard on the radio about a condition where kids walk on their tip toes, can't remember the name of it sorry, but it had 'equine' in it because of the way horses walk or something... ugh, not making sense... what's new?!

IMO, if he CAN walk normally, just chooses to tip toe, there shouldn't be a problem & he'd get sick of it eventually?!

Sorry I am no help... hope somebody has some more info for you...!!
