Anyone experience having a hard time letting certain people hold your baby?

I’m really anxious about letting my MIL hold my baby. It’s not like she’s going to steal him or drop him... she’s just not been kind to me OR my husband (her son! who I’m obviously protective over). I don’t trust her and she just makes me feel gross, I guess. I almost feel like she doesn’t have the right to hold my kid after she’s been pretty awful to us.

Anyone have experience with something like this? How do I calm down and include everyone, even when it’s uncomfortable to me?
