Query: Amazinly wonderful book!

I love this book. My son is 8 months old and has never slept more than an hour and a half. Today is the third day. The first day he cried 1 hour and then he slept 5 hours and woke up to eat and then had some trouble beig comfortable the rest of the night. The second night he cried for 20 minutes and slept 7 hours then woke up to eat and slept another 4 hours. It was absolute heaven! His naps are going much better too. Im soo excited!!
