I hear you all about mandatory nap time, but I just want to share my experiance with my own daugther. She was 2.5 when she started at a daycare in the neighbourhood, her and 2 other 3 yos were the only ones that napped while the older kids (my son included who was 4) had quiet time (movie, or puzzle or whatever). Now I have ALWAYS been strict about our bedtime routine, as I learned with my son, its a necessity!! On the rare occasions they did give me any trouble you can belive my foot was already down!! LOL! My kids go to bed very easily even now at 5 and 6years old. However, I did notice about 2m into our daycare arrangement, despite our clockwork bedtime routine, (ended in bed at 8pm) she was still awake at 10pm. On the weekends and holidays when she was home with us, she stopped napping all together and was suprisingly fine, bedtime was normal. However, after speaking with the provider even though she was waking after an hour now (down from 2 hrs) she still maintained that she needed that nap and flat out refused to let her go without to see how it went. So her late nights continued. When we left care, she stopped napping all together and really very few problems with the adjustment. My son at 3.5 had more problems adjusting to no nap than she did. So being on the other end of it, I try to be flexible regarding nap time, of course if the child is miserable b/c of missed nap, then she's clearly not ready, but sometimes I think it is possible that they are ready to give up that nap at a younger than average age.... I must say that as a parent I was slightly miffed that my provider did not think I knew what my child did (or in this case did not) need and would not work with me that way.... especially since she already had so many non-nappers.

Although it does sound like this little guy still needs his nap, he just needs to get used to going to sleep w/o his mom. I think if he's co-slept all of his life it would be a big adjustment to make for him to go to sleep w/o his mom at daycare, but I would imagine if you are consistent and give it some time he will learn to do it, hopefully sooner rather than later!
