My early emotional breakdown over the absurd amount of toys my kids have

I’m Brazilian, married to an American, living in the US. I grew up upper middle class with two sisters, and growing up, we had, combined, a toy box worth of toys. Not because we couldn’t afford more - because we didn’t need more. I always assumed it would be the same for my kids.

Fast forward to me having my own kids. My MIL’s love language is gift giving, and I feel like every year my kids are given an absurd amount of toys for Christmas to join the collection of toys we’re already drowning in. As a Brazilian, I truly don’t understand wanting to have the type of toys at home that are at playgrounds, or that my toddler plays with at the indoor play space.

I feel like there’s something getting lost in translation and my husband’s family is so passive aggressive that I feel like if I was direct with her I’d come across extremely rude, so I’ve (cowardly, I recognize) ended up just putting up with it year after year instead of voicing my thoughts on this. They ask what the kids want for christmas, I tell them two things for each of them, and instead of getting these two things, they get the two PLUS ten other things each.

I’m crawling out of my skin at the amount of things in this house. I’m typing this as half of the family room is taken over by toys I’ve decided to donate. I’m determined to make it clear that next year we want non-physical gifts. Memberships to the children’s museum; the zoo; gift cards for the indoor play place, etc.

I don’t know what I’m looking for with this post. Commiseration? A reality check? Are my feelings valid or am I being ungrateful? I’m Catholic and every year the Christmas season makes me sad because it feels like it revolves around fulfilling my husband’s family insane consumerist impulses than it is about the birth of Christ. I don’t like the expectation of what Christmas is about that this inevitably creates on my kids or the feeling that I’m failing at Christmas every year by giving the kids less things than they do.

Edit: I typed “yearly” wrong and now can’t correct the title 🤦🏻‍♀️😂

Edit 2: thank you so much for all the replies. I feel a lot better after venting and after seeing so many other parents feel the same.

To address a point that has come up a few times: I am completely aware that this is an extremely privileged complaint. And that’s part of the reason the whole thing makes me feel so crummy. It’s excessive, and I have guilt over not just feeling grateful.

I agree with most comments that I need to get better at donating toys. If my tactic for next year doesn’t work, I’ll do that instead, but the plan I came up with is to ask (to have my husband tell her, actually) my MIL for “experience” gifts, for which I have a whole list of ideas, and she can get them one toy if she wants something for them to open on Christmas morning. Clothes and stocking stuffers are fine too.
