Mother in law rant advice please

Hi, so just to start off my mother-in-law didn’t really bother with me during my pregnancy if anything she called me dramatic when I was suffering with morning sickness she invited herself to our gender scan and I just really don’t like her at this point, my baby is nearly 4 months now every time we go to her house her or my father-in-law constantly have to be holding my baby I can never hold my own baby when I’m there it’s always them to pass him around and it really frustrates me because I just feel like we don’t go there just for them to see their grandson like I want to be able to hold my own baby I struggle with confidence. I am a people pleaser but it’s just grating on me so much now. She says strange things to my baby such as oh you idolise me, don’t you? And just says oh are you acting hungry with me because I feed you all the time? Or is your mummy and daddy not treating you right? Are they horrible to you? And I know my baby is only four months and does not understand this, but it really angers me. I feel like she is overly obsessed with him if she is holding him and anyone else tries to talk to him or interact with him she tells them to go away. Not me but like her husband I really don’t like her. My partner doesn’t stick up for herself either. I don’t know if I’m just being dramatic. I am quite territorial over my baby but I just want to be able to have the confidence to say I want my baby back now please or can you not say that I don’t feel comfortable with you saying that?
