I purchased a book twelve hours in twelve weeks. It's a highly recommended book and thought I'd share that I've read and followed the guidelines and my baby is 9 weeks old and currently only has one night feeding so she is sleeping basically from 7 at night to 7 in the morning with one nap in morning and one nap in afternoon. The book is about getting your baby to sleep all through the night and a lot of parents have had success with it and thought you guys would like to check it out if your interested in getting more sleep. Twelve hours by twelve weeks old and you basically start the sleep training at 9 weeks! Get it ! If you can!!
