Stop buying stuff for my baby?

So, my husband and I got pregnant in January, before COVID really hit. When we realized that the quarantine was going to last for a while, we decided to go ahead and buy up things for baby. I found a coupon for the stroller/car seat combo I wanted, and bought it. Carter’s and other baby stores began having huge sales, so I’d order some clothes and shoes online. I bought my own diaper bag, as well as some bottles, blankets, and some other small things (like baby spoons or bottle cleaner).

I bought all of this because I didn’t think I’d be able to have a baby shower. But, now that things have began opening back up, my family is planning a small (like 15 people) one, and other people have mentioned shipping me a gift. That’s great and I am so grateful! But I don’t want to rely on other people to buy stuff for my baby.

My MIL found out that my husband and I bought the furniture, except for the crib, yesterday and got super upset. She keeps saying that we’re not giving anyone else an opportunity to buy for the baby, and do not buy a crib because she wants to buy it. That’s awesome and I’m grateful, but she has continuously made comments about me buying things.

Am I wrong for buying this stuff? There’s still plenty of things on my registry, ranging from baby mittens or hats to a swing or pack n play. There’s plenty left to buy, but I don’t want to rely on someone else to buy for my own kid. I don’t want to “expect” that from someone else, especially higher price items. Like, she said I shouldn’t have bought a car seat, stroller, or the furniture. I’ve never gone to a baby shower where someone gifted a changing table lol.

I’m just tired of getting things ready for the baby, but then my mom and MIL both always say I should stop. My husband and I didn’t think we would even get anything as gifts or a shower, and almost all of these purchases were during quarantine. I keep telling them that there’s still plenty of things that we need on the registry, but they won’t even go look at it! 🤦🏻‍♀️
