Query: Disturbing...

I haven't read this book, but I was browsing through and found it. The title is disturbing. A newborn, even at 3 months, needs to eat at least every 3-4 hours. I don't know how the author proposes to keep a child asleep even when they are hungry, but I hope it doesn't involve reverting to formula instead of breastmilk just so the parents can sleep a little more.
