After 5 minutes, I stopped, gave him the pacifier, and held him until he burped. He seemed very calm and went limp after a minute. I figured he was asleep, or well on his way, so I laid him down in the crib, and went back to bed myself. It was 10 after 4. Well, 5 minutes later, just as I was starting to doze off, he woke up and started crying again. I went back to trying to comfort him, but he wasn't having it. He seemed to still be hungry, so I gave him the other breast for another 5 minutes. He was much more limp and relaxed after this feeding, and fortunately, he fell right to sleep. And stayed asleep. He was then up at 6:40 to eat again, and up for the day at 7. It was a long night.
The 2-3-4 nap schedule has been working out great during the day. And when we first started the new schedule, his stretches at night got longer. But now they're getting shorter again. I don't know what's going on. It seemed so perfect at first, but now it's getting worse. I guess we'll just have to keep trying, and stick to our guns about not feeding him during the night. Hopefully he'll get the idea that he's not getting food, and he'll either stay asleep, or put himself to sleep as soon as he wakes during the night.
