Kayci Won't Sleep

Last night was rough. First, Kayci decided to bypass her power nap at 6ish and just go right to sleep at 7. That was fine, except when she woke up at 10 thinking she had just gotten up from her power nap and wanted to play. She didn't want to go back to sleep. Every time I tried to put her back down in her bed, she would wake up immediately and either cry or want to play. So we brought Kayci to bed with us, where she went immediately to sleep. She's old enough and aware enough now to know where she is and to like sleeping with us. However, neither of us sleeps as well when she's with us. Also, we've gotten her in the habit of needing one of us to hold her and rock her to sleep at night. So now we face a challenge: is it time to let her cry it out one night? Kristi doesn't think that going cold turkey is the answer. She thinks we need to go back and consulty the books and try to gradually get Kayci to put herself to sleep. I don't think there's any real way to do that. I think that if she fusses for a little bit she'll put herself to sleep without one of us having to hold her. Of course, the ultimate goal is for Kayci to go to sleep in her own bed by herself and to sleep there through the night. We just don't want to break her in the process, but she's getting (or at) an age now where if we don't make some tough choices it will be tougher to break her of some bad habits later.
