Have you tried just giving him a cuddle when he wakes? Instead of just popping him straight on the boob, pick him up, talk to him, cuddle him, soothe him if he gets anxious. Us mothers have a wonderful way of being able to soothe baby just using our voices, our touch. In a newborn it is especially powerful.

If you are in bed at night, he could lie between you and DH, kick his legs up a bit, look up at you? Alternatively have you got a soft nightlight or toy that glows that you wave in front of him?

Just a few idea... hope it helps...
