Have you tried slipping a pacifier into his mouth after he's sleeping and around the time he usually wakes up? Maybe that would trick him into not fully waking, at least during the night.

I agree with glatt and the ped about him needing solids. That to my mind would be the one biggest reason why he's not restful. It worked like a charm with my boys when they were babies. As soon as they started on solids before bed, they started sleeping through in their cots.

Have you tried different types of food? (I'm guessing the answer is yes) Sometimes kids like the weirdest things though. Maybe do a bit of experimenting outside the box?

Sorry I couldn't be more help.
