Baby Ball problems eating.

[moonsongs]

I have had my baby ball, he's about 15 inches, for about a month a half. I have tried to feed him frozen and pre-killed mice, of the appropriate size, but is not interested in them. When I tried to feed him a live mouse, he was definitely interested. The problem is that when he attacks the mouse and coils, he doesn't seem to be strong enough to suffocate the mouse.
So, the mouse gets free and then the snake balls up and that's the last of the interaction. I'm afraid that since he's a baby, he isn't getting the nutrition he needs. Is there anything I can do?
