My mother thinks my child is hers

So my mother wants to baptise my daughter she’s told me she feels it’s important as the child is innocent and she wants the child to follow her with her religion but I disagree as I stopped going to church at 16 and no longer share the same belief to her extant and my fiancee has never even attended a church but we do plan on giving our children access to religion as they grow up so they can decide what makes them happy as I was forced to go to church growing up and it didn’t give me the best experience as I didn’t enjoy it and had no choice in the matter but to go each Sunday I don’t want to force my mums beliefs on my child as she already has 14 grandchildren and I didn’t see her act this way with any of them but she states it’s because I’m the youngest of all her 10 kids and I’m supposed to be different but I don’t see it that way all my life Iv been told I didn’t have a voice in my family because I’m the youngest no matter my age and now I’m 21 she still thinks she can have a hold of me and my baby’s future I think it’s completely wrong and just looking for advice on how I can tell my stubborn mum that my child will not be getting baptised or forced to attend church with her until I believe my child is ready as my daughter is only 2 months and my mum is already calling shots on her schooling and is acting like my daughter is her child and is telling me I know nothing about a child because she still thinks I’m a child myself before my due date my mum had even given me adoption papers as she wanted to adopt my daughter and tried to convince me I couldn’t do it but my older sisters who are now in their 30s had kids at 17 and 16 and my mum did not attempt this at all idk if it’s cause she’s older now and is wanting a child of her own but one thing is for sure she will not have my daughter around her toxic traditions and my toxic siblings
