The Cribside Method — Find the real problem, and fix it tonight

For 0–24 months. Read it tonight. Change one thing tonight.

It is 3am. You have tried the swaddle, the shushing, the drive around the block, and two things you read online that said the opposite of each other. You do not know what the problem is anymore.

Instead: you answer a few short questions and find out which of five things is keeping your baby awake — and the one change to make at the next wake-up.

This is the book the other nine are built on. It shows how baby sleep works, what the research really says, and where the usual advice goes wrong. Start here if you do not know yet what you are fixing.
