Should I ask my MIL to stop?

For the last year or 2, every time my MIL visits my husband and me (and our baby) she brings a ton of homemade food. Like enough for our lunch and dinner and sometimes breakfast for a whole week. I appreciated it when I was postpartum but at this point it’s becoming too much, bc I don’t even have room in our fridge and freezer to cook my own stuff (I love to cook). They visit about every other week and sometimes every week.

I found out last month that my husbands grandma has been telling everyone he looks too thin and I should be feeding him more meat. After that, his parents brought us a ton of cooked meat. And now when his mom brings food, she tells me which food I should freeze so nothing spoils. Last week, I told her oh ok yea we’ll probably leave it all in the fridge because we’ll eat it this week. And she actually started arguing with me saying which specific food I should really put in the freezer because they’ll be coming back next week and will have more food and then they won’t see us for a few weeks so we should have a stash in the freezer.. like micromanaging my own refrigerator as though I’m incapable of rationing out food for my family.

I’m perfectly capable of shopping and cooking for our own food. Should I just be thankful for their ‘help’, or is this a condescending thing they’re doing to me? They give us a lot of food and it’s obviously helpful to not have to cook so much. But if this is some way of them looking down on me id rather not accept it.
