My MIL told my husband she wanted to keep our 7.5 month old son overnight at her house in a few weeks. My mil has a really hyper, somewhat aggressive dog that stays indoors. Her boyfriend also has a really bad drinking problem. He drinks and drives, starts yelling at her when he drinks, etc. My husband told her today that we talked and don’t feel comfortable with him staying the night there due to the dog and her drunk boyfriend. She burst into tears, stated none of her other kids ever had a problem with it, etc and hung up on my husband. He wants me to try to talk to her, but I feel like I should give her time too cool off first. My mil already doesn’t like me. How would you broach this topic? Or would you just let it go?
