I don’t mean to be rude, but since you have posted this I will be very honest, "YOU NEED TO GET YOUR HUSBAND SOME PROFESSIONAL HELP!!!"
This may be a very difficult topic to comment on, but there is A REAL problem, and I think that you should go and speak to someone, not on this site either.
I don’t think it matters even IF your baby doen’t understand, your husband and you do, so I don’t think this is NORMAL PARENTING behaviour!
