In conjunction with learning how to stand, Kiddo forgot how to put herself to sleep. Putting her down in her crib led to much protest in the form of heart-wrending cries and sobs. She would only fall asleep if she was rocked and rocked and rocked, and even then it wasn't clear that she could be easily transferred to the crib. When it was only her naps that were being effected, it was challenging, but when her frustrating sleeping patterns moved to her night sleep as well, I was not okay with it. After two or three nights of going in and out of her room to help her fall asleep, I had had enough.
So last night we sucked it up, and "reset" her sleeping patterns, by letting her cry it out. I hate doing it, and am no good at it. But we did. She finally fell asleep, and this morning, went down for her nap with limited protest. It's nice to have things settled again.
