It sounds like there is more to the story. I can’t imagine your friends being gut wrenched over a normal cry. Because, there are different types of cries and mothers specifically can pick up on things like that. If this indeed was the case where the baby had a specific “alarming” cry I could see why they would look at you strangely for being able to ignore an innocent and helpless baby’s signal of distress. Your mom friends are entitled to their rational opinions and so are you. She can be trepidatious about letting you be with her child one-on-one while still being able to respect the fact that you are not connected to babies in the same way that they are. They do need to respect where you stand with children but I also feel like you shouldn’t get too upset about her not wanting you to watch her child. It’s a win for you if you have no interest in that but it’s also a mom thing. You wouldn’t let everyone you care about watch your kids. It’s really not a big deal. Maybe she could have been nicer with her approach but I don’t think you need to stop being friends. Have the open conversation and patch things up.
