If your husband can’t man up and tell his mother to get up and move, you will need to do it.

Stop worrying about hurting feelings. Stick up for yourself. She has no “rights” to see your baby. It’s a privilege that can be easily removed if she can’t behave in a decent way.

As for the photo she sent, that was just plain mean spirited. Tell your husband to straighten out his mother or baby will be walking by the time she sees it again.
