Help I dont know what to do 😑

So don't get me wrong I love my mom but sometimes I just smh at some of the stuff she does. I am a very minimal person and I like particular things so for Harrison on the registry I picked things I want. Well my mom doesn't even look at it and just starts buying junk or used old items. Prime example she said don't worry whatever crib you want I'll get.. I show her a really nice one that turns into a bed so we won't have to buy another bed again and she gets one off craigslist that's 10 yrs old with a recall in it!!! Then since I told her I won't use it she buys a cheap fisher price one.. Again why ask if you're not going to actually get it.. Then I had a nice glider chosen on my registry and she just shows me today again another one that looks old and scary from a garage sale falling apart! She is like if you don't want it I'll just keep it making me feel guilty. I just want her to stop buying stuff!!! Part of me is just wanting to say whatever you want to give put on a gift card and I'll take care of the rest!! Anyone else have a bargain hunting hoarder of a mother??
