He needs to eat more all day every day (not just before bed) for 3 days (takes time for body to register the change), and then you'll see he won't wake at night. My Aunt has 10 kids and taught me that trick. I thought my baby was full, but sure enough by feeding even more all day for a few days-she never woke again at night. Worked for my next two babies too.
