A New Way to Sleep

We've been struggling with Nate and his sleeping for about a week now (a very long week). It started last Thursday night when he screamed for hours & hours - even while you were holding him, nothing would comfort his. I ended up holding him for four hours while he slept & then Tony took over & he did sleep in his crib for a couple of hours. We are not sure what this was about, but he did have a little bit of a cold. Teething, maybe, no teeth yet. (He had night like this when he was a few weeks old.) Since that day getting him to sleep has been quite a chore, especially now that he can roll to his tummy. He doesn't stay swaddled anymore, but he can't comfort himself if he isn't swaddled. His hands are out of control & pull his binky out. Last night, we decided he has to learn to fall asleep on his own, not swaddled. After about 4 hours of crying last night, he finally fell asleep. Today, he fell asleep pretty quickly for his morning nap, but it took him an hour of crying to fall asleep for his afternoon nap. Both times, he has fallen asleep on his tummy. Hopefully, he will quickly adjust to sleeping without being swaddled.
