Wasn't it just a few days ago I was saying it seems like Mari has finally learned to nap? Uh, perhaps not. She slept for only 45 minutes in the morning but seemed fine when she woke up, so I didn't try too hard to get her back down. But in the afternoon, she woke up after only 25 minutes of napping and this time she was whiny and still clearly tired. So I tried to rock her back to sleep, as I used to do when she was a little baby. I haven't often had success with that technique lately, but today she did manage to drift off again after about 10 minutes. After she seemed good and asleep, I tried to put her down, but she started to cry again as soon as I so much as twitched. Fine. So I rocked her back to sleep and this time I held her even longer before even trying to put her back to sleep. I waited until my arm was asleep and so tired I was afraid I'd drop her. I tried moving just a tiny little bit -- nowhere close to putting her down. She screamed. I ended up holding her for a total of 45 minutes (including the first time I rocked her to sleep), until she slumped over in my arms and woke herself up. I haven't had to hold her for a nap for months. At least it bought her a little extra sleep, so she was in a reasonable mood when she got up.
What's going on here? Is this the eight-month sleep regression?
