Annoying

Does anyone else’s mother in laws call your baby “their baby”? She always has. I understand she’s her grandma but it’s weird because she’s always calling her “her baby” and introducing her as her baby. Not her grandbaby or her name lol. I mentioned it and she said “well she’s my baby too.” Like okay?? I’ve never heard that before but it’s getting annoying and I know she probably doesn’t mean any harm, but it’s all of the time. If we’re in public or anywhere and she’s around she instantly takes my daughter from me and doesn’t give her back even if I tell her then I have to literally force her to give me my child. And she always has to walk away from us and we have to try to keep up because I’m like hey I need to know where my kid is lol. I don’t know maybe I’m just weird and it’s not a big deal.
