So just curious if anyone else has to deal with this and how you deal....

A little back story, my sister in law and her husband desperately want a baby (she has an 8 yr old from a previous relationship) and they recently found out he’s sterile and she has a low egg count. So everyone kinda walks on eggshells because she so desperately wants a baby.....in the meantime she is obsessed with my daughter and here’s the thing...my daughter isn’t super comfortable with her. She cries a lot with her. They were over tonight and my daughter was fussy with her but fine when I was holding her. My sister in law will take her and not give her back even when she’s screaming leaving me having to either let her cry or forcibly take her back which is obviously what I opt to do. It’s so stressful and frustrating for me and I feel like my husband lets her get away with it because he feels bad that she can’t get pregnant. When someone else has the baby and she starts crying I’ll give it a hot minute to see if she will settle but when she doesn’t stop crying I want my baby back, everyone else respects that even my mother in law. I have a fairly good relationship with my sister in law normally but after tonight I’m irritated and stressed out at what went down. Anyone else deal with anything like this?
