My aunt

I have this aunt I'm fairly close to, she never had kids and is really excited about this baby. She is helping us out a lot with house projects that I'm really thankful for and told us she would buy the crib. She also just bought a rental house that came with a ton of furniture, so we basically get a ton of really nice furniture and can sell whatever we don't want. But she is also searching second hand websites and asks me at least once a week if I want big items, like a pack n play, car seat, swing, etc. as much as I really do want these things, this is my first baby (first baby in the family) and I really want to pick stuff out myself and get some of these new. Especially car seats and strollers. She is also really emotional going through menopause so she gets her feelings hurt easily. My mom doesn't even know how to stop her. I'm just not sure what to do at this point. I don't want her to spend a bunch of money on things I don't want either.
