I also found "Healthy Sleep Habit, Happy Child" very useful. We haven't had to cry-it-out yet, and I am not sure how I feel about it anyway. The other information in the book on how babies learn to sleep is really useful. I think we have been mostly lucky with a good sleeper, but organizing her days and nights a bit helped. I wouldn't have known to do it without the book.
We may be at a decision point for cry it out or co-sleeping after three days of crashing at a friend's house and hotel while really sick and stressed out. She has slept with me/us for the past three nights... Good luck with Allison. My daughter is nearly the same age and starting to wake up more now. It has almost always been due to sickness so far, but I can see her waking up to play on occasion. Teething isn't going to help matters if it ever happens.
