Input: Ok Reddit, for this you'll need some backstory. I'm a 16yo girl who's lived alone with my mom and cat for the last 4ish years after my mom kicked my brother out. About a year and a half ago, my brother(21) announced that he got his girlfriend(35), pregnant and that he was bringing her, their kid, and her older kid down to live with us around Christmas time. Long story short it ended up being 3 kids, instead of 2 but we just kinda shrugged it off. 

Now, the girlfriend is extremely immature. She loves gossip, "drama" and is extremely lazy, think of her as a high school freshman essentially. One of her kids is a girl a month younger than me and, while she stayed with us, she was watching the baby more than everyone in the house. She fed him, changed his diaper, carried him everywhere, bathed him, etc. She was basically his mom. Now the reason she could do this all day despite being a child, was that she was homeschooled, but because she spent so much time watching him, she never did any work. Eventually her grandma, girlfriends mom, came down to visit. She was the one who kinda spilled the beans on everything, saying she was glad her daughter came down here because she didn't want to raise another one of her grandchildren (she p much raised the older kid.) The older kid eventually left with her grandma, her reason being that she "didn't want to be a babysitter anymore."

Now here we are in present day. The job of babysitting was transferred to MY grandma, until my mom called them out of it, and then to her 13yo kid. Now like I've said before, I've lived alone for the past couple of years, I'm an introvert at heart and prefer to stay away from people. If anyone's been super affected by these guys moving in, it's my 14yo cat, Shelly. Once the baby started  walking, his favorite place to be was the laundry room, in here he would turn the laundry on and off and eventually start eating cat food (this later turned into dropping cat food into her water dish.) His mom never stopped him from doing this, she'd just say, "Ky, stop." And leave it at that. Their move in general caused my cat a lot of stress, but this threw her way over the edge, she started defecating and urinating outside of the litter box, became a lot more vocal and would only go eat at night. Now, I didn't mind cleaning up after her, my problem was that my mom was threatening to get rid of her because of this. I've had this cat since I was 3, there was no way in hell I'd give her up cause some milf can't watch her kid.

A few nights ago, my mom and I asked her if she could try to keep him out of the laundry room (keep in mind that his actions alone raised my mom's water bills to $400+.) She became super defensive, saying that she can't watch him 24/7 cause then she "wouldn't be able to do anything but watch him." She then got mad at me for "blaming him for being a baby" when in reality I was blaming her for not watching him. This really pissed me off because, even though my cat's actions aren't my fault, she still complains to me about her going on the counters (searching for clean water in the sink) and crapping on the carpet. I still take responsibility for my cat, but she refuses to take responsibility for her son.

TLDR; My brother's girlfriend doesn't take responsibility for her son's actions and considers me an asshole for wanting her to watch him more.
