It’s fine to ask. It’s not fine to demand.

"Your failure to use birth control is not my problem."

This isn't just a childless thing either --folks assume if you have a child you want to watch theirs. Uhm, no. I'm a firm believer in "you bring em you're responsible for em". Yours are quite welcome to play with mine... But if you leave, your kids go with you. I don't care if it's just "a quick run to the store". No. Unless we have worked it out ahead of time (and even then the answer will probably be no!) you are not leaving your kids with me.

Unpopular take, but I like the comment that said to visit the parents on their own, "not when the circus is in town." I feel like the siblings have established a pattern of expecting help whenever there is a family gathering, so continuing to show up and refuse to help is just asking for drama. Have your child-free holidays, and the family gatherings can be all about the kids, which is how everyone seems to want it anyway.

wow, not even one YTA to be seen... there's usually at least one.

Ultimately, it should be the people who had the kids who are responsible for them at all times. If a relative likes kids and wants to help out and volunteers, that’s one thing, nobody should be pressured into doing things for children that they don’t want to do anything for. Like people with pets expects everybody love cats and dogs because they do.

Gf gets screamed at by younger brother when she isn't available to watch his kids. They're in their late 20s and have expectations to go out every night and live like people who don't have any kids. Sorry, but start doing things as a family and stop expecting others to take care of the kids you decided to have. They had a live in nanny with his mother, but the expectations to be the primary person raising their kids among other wild things drove her to move out and now they're mad at her. It boggles the mind and entitlement is a disease.

Definitely NTA. Bravo for saying " No" to something you don't want to do & it shouldn't be assumed that you're going to be at their beck & call just because - in no particular order: 1) "they're family, 2) you don't have children of your own to look after so you're not doing anything anyway, 3) you're there, & 4) you're a woman. It would be interesting if, "somehow," they got the idea that you don't have a CLUE how to do all those things. When one ihas been squalling his head off for ages, offer to go in get a beer to put in his bottle, "I read that'll make kids really calm." "He needs his diaper changed NOW? Don't you just put one on in the morning & put on another clean one the next morning?" "Baby food? That smells gross! He's got some teeth - I'll get him a hamburger or a hot dog or a couple ribs." "Oh, come on, it won't hurt him to put that in his mouth - I read it's better for babies & toddlers to be left on their own to explore & they just innately know if something's not good for them." "Car seat? It looks like it's made for astronauts. Just hold the kid on your lap & put your seatbelt around him too." "Awww, he looks so cute with ketchup in his hair! Come here, Purvis, Jr - we'll add some mustard & make a pretty color & then Auntie will pretend it's styling gel & make your hair stand up in spikes like the big boys do! Tell Mommy you want spikes!" "Attention, everybody - we have an announcement. Our family is about to get bigger! Yes, we're getting a puppy! And we're going to bring him next time! The kids will love it! I hope we won't make a mess in the yard but we can all just be careful where we step & pick up after him. & We'll put his food dish under my chair so he won't bother anybody & try to take food off their plates. We've got it all planned out & it'll be such fun, especially with everybody pitching in to take care of him - he'll just be another one of the babies!" OK, OP is more direct & it looks like that'll work if she sticks to her guns & they finally give up. I just like yanking people's chains when they're being obnoxious & out of line. About all these single moms ..... wait! There are dads there too? & What are they doing? & Why don't the moms go to the dads for them to do their parental duties rather than bothering OP?

I would have used the "Not my circus, not my monkeys" line.....with a looooong look around the room as I said the word "monkeys".

Okay, first of all. Helping with children should be voluntary..
