Different Faiths in ONE House

I am Christian and my husband is Jewish.  Until we had kids, everything was fine, but now that our kids are 6 and 4, we are starting to have issues with which way to go with religion.  I just assumed that we would raise them in a neutral houshold, becuase we never really followed any faith while we dated or the 4 years we were married.  NOW, it's becomming an issue . . . but I am not comfortable with the Jewish faith . . and he is not comfortable with the Christian one.  I need some help!  We SHOULD have talked about it before, but it's obviously too late for that. ..
