We've just started getting her on a 4 hour EASY this week, and started pu/pd to help her learn to fall asleep on her own. Prior to this it had been a loose 3-3.5 hour cycle based on her varying nap lengths (they were typically 40 minutes but we never knew). So right now because we're getting her on a real routine for the first time, we're going by the book for the week and watching the clock. Yesterday she was right on track: up at 7, eat, play, nap 9-11 (she didn't really get to sleep until about 9:30 because of pu/pd), eat, play, nap 1-3, eat, play, catnap 5:15-5:45, play, eat, bed at 7:30, df 10:00. Then the little NWs started. At 2:30 she was really hungry and nursed. A couple more little NWs until 6:00 when she was really up. She might have drifted in and out of sleep and play because there were periods of quiet from 6-6:30, and then she was up and crying. We got her up to start the day then just quietly hanging out with her until 7 when I fed her and started the day for real. Yesterday's ideal timing of the day was not normal for her though---like I said, she had previously been doing several short naps/day. Her morning nap started well today but she only slept 40 minutes or so--there's a whole post on the Naps board about that one.... We did pu/pd and such for the remainder of the nap period, but she never went back to sleep for that one. Thankfully, she's napping now and went to sleep very easily for her afternoon nap. The initial going to sleep has gotten very easy, but it seems like she's still working on what to do when she wakes up and isn't really tired anymore.
