Yes, the crying issue stopped after DS2 dropped his nap (shortly after turning 3). DS3 will be 3 this summer and he is still napping. It seems like he doesn't have bad wake ups everyday now, like before. He'll have a day or two a wk where he wakes up and is in a great mood. I really don't know what is going on, except that DS2 and DS3 both have very intense and sensitive type of personalities. When they sleep, they sleep much more deeply than DS1 does. I mean, DS1 used to wake up and SING and make happy noises when he woke up, I guess since he was my first, I thought that was normal. Then I had DS2 and I was like WHAT? DH and I have never understood how DS2 and DS3 could manage to wake up from a nap, crabbier, than before their nap. What was the point of the nap???
