Who needs sleep anyway

Naomi has decided that after almost 18 months of giving us very little problems in the sleep department, that it was time to start challenging us. We've been having a hard time getting her to sleep on her own at night. And when she wakes up in the middle of the night she hasn't been going back to bed on her own unless we go in to soothe her. Last night was the worst when she decided she didn't want to sleep from 1am til 7am!! We definitely got her out of the routine of sleeping on her own when she was sick and we'd stay in the room with her til she had fallen asleep. But now that she's better, Austin and I decided it was time to for sleep training. We had used the cry-it-out method when she was a baby and it had worked really well. She never cried for more than 20 mins and within a few days was going to bed without crying at all. Now, she could probably cry for hours and hours if we let her. Seems we usually end up caving in and going into to rock her again. Maybe we're just perpetuating the problem here, but it is SOOO hard to let your kid cry when she's screaming out mama and dada!! Today I checked out 4 books from the library with various titles such as "the no cry sleep method", "baby whisperer" etc. So far most of them are kind of hokey and stuff we already know/do, like set a good bed time routine etc. I just hope we get her to get back into a good sleeper soon!!
