Re: Advice needed- MIL
MIL's are painful!! My MIL thinks the sun shines out of DH and I've taken him away from the family. Meanwhile he doesn't see them much because they treat me like dirt.
You are in a slightly better position that she seems to spread her resentment equally. What I think you both need to do is put your foot down with her. If she can't be nice, she isn't included. Period!! End of!!
Your new baby is a special gift, regardless of what MIL thinks.
