I'm in my 2nd month with a 13 month old who is still doing lots of screaming and not napping as long as all the others who are into a great routine. But my little guy is still part-time and I find they never settle in properly until the Mom goes back to work full-time and the child is here 5 days/week. But he's dropped his morning nap here and I think that's really affecting him badly.

Children really need routine and it's hard on them until their little bodies adjust. I agree with Crayola, I've nudged our naptime up to 12:30 and they fall asleep quickly and sleep great. It's great when you get a child who adjusts quickly but I find it takes a few months.
