Parents IME are always quick to blame nap time. Over the years, I have had to "alter" the truth slightly and what happens usually is mom will say please dont give X a nap anymore because she wnont sleep at night. So for the next week or so I let mom believe tht X did not nap each day and lo and behold their nighttime problems seem to go away. Imagine that. Now I have only done this in cases where I truly felt that the child needed the nap. The other issue becomes if you want tohave kids in your care that do not nap. I know that there are some providers whose policy is that when they no longer need to nap they have outgrown the daycare. good luck with this one, parents who dont beleive their kids need to nap can be brutal to deal with
