Yes, you must enforce quiet time with all the kids so you're sane to look after them. I currently have one who is a January birth kid, so he's almost 4.5 and off to JK in Sept. Plus he's very tall and mature, but i insist he has rest time for an hour. I have a little foam mattress for each of the older dcks cut to the size of a crib mattress which I've sewed a simple cover over, and then I put a crib sheet over to be able to wash. They get 2 or 3 books and i tell them "Have a good rest and I'll come back when quiet time is over. I'm going to have a rest too." Has worked so far. When quiet time is done, i just stand the foam mattresses on their sides in the corner. Good luck!
