How to make my husband feel comfortable with sex again?

Our sex life was just fine prior to pregnancy, if anything his libido was slightly higher than mine. Now that we're a few months along he is completely uninterested in sex. He feels weirded out by the baby being so close, and knows it isn't logical but can't put it from his mind. We went from a few times a week to once every other month -- which is a struggle for me since I'm hormonal AF now. He can't answer these questions himself, he doesn't know what the solution is so I thought I'd ask here -- what can I do to make him more comfortable and interested? Is there something he can do to help the process?
