Being judged for NOT brining my one year old trick or treating or even dressing him up...

Last year he was only 2 months old so I didn’t see a point of bringing him outside at all. I wanted to dress him up, but as time went by I just didn’t bother...

Now he’s 1 year old and I have my parents saying “you’re taking him out right?” I said “no I don’t see a point in it tbh, it’s cold, and it’s going to affect schedules, and he’s just too young and honestly it’s a waste of money to buy a costume right now” tbh we don’t have that much money as I’m not working...They kept trying to convince me and even said they’ll buy the costume, so I just said “okay we’ll see” because it got annoying.

They asked again. So I just said I don’t think I’m going to be taking him out. They said “we’re taking him out.” Honestly, I got annoyed because I feel like they’re going against me? I’m the parent! And if I’m going to take him out it’s going to be ME and his father as it’s his first time and they could join if they wanted. So I just said I don’t see a point, he’s too young. And they now seemed pissed?

Am I wrong here? I mean yes ideally I would like to take photos of him in a costume, it’ll be cute. But like I said we don’t have the money for it. And it seems like the only way they’re going to pay for it is if I bring him out which I don’t want to. It’s not like he has older siblings and I’m bringing them out, then I probably would bring him because that’s different! I was never big on Halloween anyways. Oh and he’s not walking yet either!
