I agree that it all depends on the child and what's happening at home. I have a just turned 24 month old who has been putting a lot of her own stuff on for months and then I had a 30month old(2.6yrs) who couldn't do a thing (dressing wise) for himself. I expected him to so made him do it here but parents did everything for him at home. You could talk to the parents and ask them to encourage this independence at home and see what they say.
