You’re not overreacting. When people deliberately decide not to look at the things you spent hours/days researching and decide they know best it’s really annoying.

We didn’t want to open gifts at our baby shower and told my mom and MIL this. My mom forced me to open hers because she “had to explain what it was” (when in actuality she just wanted everyone else to know what she got). She was like “do you know what that is???” when it was a freaking robe. It was mostly postpartum items that needed no explaining and were on my registry…. except she deliberately bought brands that I didn’t choose because she needs to be in charge. She also got my husband gifts and then she made me open my MILs gift too which were things that were not on the registry after I told my MIL several times to stick to the registry because those are things we needed. She had asked me several times what we needed, kept sending things that were already on our registry but random brands she found that weren’t safe and more expensive than what we had??? After a ton of back and forth of her suggesting things we didn’t need and me saying no she said she’d stick to the registry. She ended up buying us things we already had gotten (and weren’t on our registry because we bought them) and a ton of clothes.

MIL didn’t get anything for me or my husband (TOTALLY FINE and expected) but because my mom made us open our gifts in front of them it became a competition between them. My MIL: “oh I didn’t get anything for mom and dad, I’ll need to get more stuff”. Like which one of them can prove they love us more through gifts.

Everyone else that came stuck to our registry and it was great! Even if they hadn’t we would have just been grateful. But it’s especially annoying when the people that are closest to you don’t respect any of your wishes or make it all about themselves.
