How to get husband to stop being so jealous?

Ever since we had our daughter my husband has been weirdly jealous of me. While I was breast feeding he made a snappy comment about 'whats next, you going down on a chick on girls gone wild?'. I had no idea what he was getting at. Another time he made a similar comment and me condoleezza rice. I have no idea why he's so jealous of our baby girl breast feeding off of me. Is this normal for husbands? If this keeps up I will probably just divorce him while he's at work or something and move on. Any advice is appreciated.
