I have read The No-Cry Sleep Solution, and it had some good suggestions. I'm not familiar with the Dr. Sears book. I did find the No-Cry Sleep Solution a little tough to get through at times, definitely not in terms of reading but in terms of it being (trying to think of word lol)....can't think of one. I'm not a fan of Dr. Sears, and it's pretty Sears-like in my opinion, so maybe that's it. I haven't read Healthy Sleep Habits, Happy Child, but several people I know have, and found it helpful.

Good luck!!
