Posting for a friend as she doesn’t have a Reddit account and asked me to post for her, everything from here on, is her words and typing.

So here goes, my MILs neighbor invited me(23f), my fiance23m) and our two kids (3m) and (2f) to an Easter thing they hold every year, a glow in the dark egg hunt. Everything was going well, my son ended up finding a prize egg(paper in an egg that said prize). After we showed the neighbor he got one when they asked, they brought out one of those big eggs, it had a 5$ bill and lots of candy. She offered to take my kids baskets back home with her, as my fiance had felt bad and went to use the restroom over there and had both of my toddlers to wrangle at someone else's house whom I didn't know. When my fiance came back, we said our goodbyes and thanked everyone for including us in the hunt. We went back to my MIL house and the baskets were on the end of the couch, I noticed immediately the prize egg had gone missing. I asked my MIL about it and she said she put it away for safe keeping. My fiance also asked her where the egg had gone and she said she took it back to the neighbors (empty). Now the next day(being Easter) everything was going well, we had our own hunt, and everything. That evening I asked my MIL about the prize she had put away so my son could have it, we also planned on letting him choose a couple snacks and toys from the dollar store within the 5$ he got and if he went over we were gonna pay the remainder. She told me "I am going to open an account for the kids and put that in it" mind you #1 she didn't discuss this with me #2 it was not her money to do anything with, it's my son's money and she STOLE it(IE. Taking something that doesn't belong to you = what?) anyway, I said "ok, what about the candy from it so he can have some" and she blew up at me saying "I don't know you probably ate it bitch, get out of my room with that crazy shit" I walked out of the room and as I did I said "what's crazy Is taking 5$ from a toddler". Immediately after I said that as I was near the bathroom door, she barges out of her room and starts shoving me and demanding I leave her house(which we had stayed at for the past few months due to renovations on the house and her telling us to stay there.) She shoved me through the entire house, while I said I'd leave but I'm taking my kids with me, she yelled at me to get the fuck out now and called me a bitch multiple times, shoving me the entire time, while I had my arms raised above my head so her daughter(SIL) and her husband (FIL) and my fiance could see I wasn't doing a damn thing. Anyway, she kept pushing me and blocked me from getting to my kids. My fiance then got up and got her off of me, so I could get our kids and exit the house. I called the police, bc she had physically assaulted me and blocked me from getting my kids. All that over 5$ and candy that belonged to my son. So AITA for asking about where she put my son's money and candy?

Ik I might have been wrong to say what I did. But seriously taking 5$ from my toddler, without talking to me about it makes me so mad. Why would you need to take my son's 5$, with which we had been saying we would let him pick out some stuff with it that day, and first off saying you didn't touch his egg, but somehow have his 5$ and apparently about to put it in the bank. Am I in the wrong to even question it? Not to mention my FIL came at my fiance with a heavy metal object in hand, and when my fiance defended me and himself, my MIL tried to play victim. Especially after the cops showed up. But as I was always told "don't take stuff that isn't yours" and "don't put your hands on people". I'm really tearing myself apart about this.
