Any baby sleep training book to recommend? I prefer NO cry-it-out method.

You can consider this book "Sleeping through the night" by Jodi Mindell Ph.D. My friend refers to this while trying to sleep train her boy and found it helpful. It is available at the NLB: http://singapore.lib.overdrive.com/43740340-87DD-440C-8B22-CC8EDC5892A0/10/50/en/ContentDetails.htm?id=C21E1F91-CDE6-4BFB-8210-6262AD82FDE6
