Being 23 weeks and told to stop buying stuff. 🙃

I'm 23 weeks and I've bought baby stuff for my daughter of course but my mother in law will not shut her mouth and telling me to stop buying stuff 🙃. I feel horrible for saying that but this is my first pregnancy and if I want to enjoy buying stuff I will. She has also told me things about names we've picked out about how it has no meaning even after I told her it's my grandmothers name that's passing away. She also told me after I showed her the car seat and stroller set I liked no that it was ugly and stupid to go with the the theme I wanted, then went and looked at other strollers sets and said they're better. If she doesn't like something I'm going to BUY with my own money it shouldn't matter to her she's not getting it for me and it's not for her. She was also invited to one of my ultrasounds by me and my husband and after it she tried to take the cd we got and the pictures saying it was for his daddy, no it's not. It's for me and my husband then she continued to argue with him about it and kept taking out his hands. She's also told me things about how she will not need a infant seat and when she's tired and crying she will give out child tea. I have actually talked with her about all these things but she plays like she doesn't understand. She also gave us to every every large bags of toddler clothes and said now I can stop buying things because she knows my baby will come out big. OKAY THIS DOES NOT MEAN SHE WILL WEAR A DAMN 2T AT 3 MONTHS.
