NEED help with baby waking frequently PLEASE!!?

From my experience, I would say he is hungry. Try giving him a small amount of rice cereal mixed with milk before bedtime. Just because he is in the 75% does not mean that he is not hungry.... after all, you did say you have twins.... I has this problem, and when I told my mother-in-law, it was she who suggested this old remedy. It worked like a charm. One tablespoon of milk/cereal mixture, and my son slept through the night.
