Nah I don't think so. They really aren't in the high chair long enough for it to be an issue I would think. Personally I find the foot rest on ours to be annoying for 3 reasons...1st being that it is a wonderful helper for the little one to climb up into the highchair when they get to the climbing age (anyone care to guess what DD's favourite trick is ATM ) so it's kind of a dangerous addition IMO, and 2nd it's not adjustable on mine so is a waste until they are big enough which with my kids is 18mths+, and 3rd it collects dropped food and then they tread their feet on it and get food on feet as well as hair etc...

I have a peg prego prima pappa BTW.
