Does anyone know why it bothers some girls so much?

My husband (M, 40) and I (F, 38) both have good jobs. We tried to have children for years, but in the end, we decided to accept that it’s not happening. We are now a two-income, no-kids family. On the other hand, my sister was a single mom of two by the age of 26 ( never married , kids have two different dads and both left ) , then met a single dad of one (so a total of 3 kids in the house) and married him right away. Since then, they have had 5 more kids ( total of 8) . Now she just announced she is pregnant again. She doesn’t work, and he works long hours and doesn't lift a finger at home . Now my parents and my sister are pressuring me to pay for my nieces and nephews' nanny! I told them that my sister made a choice, so why should I sacrifice my savings (I paid for my own college and saved up instead of splurging)? My sister said my nieces and nephews are the closest things I have to a child, and I'm selfish for caring more about my dog and cat (I buy my nieces and nephews presents all the time; she is referring to my pets being loved by my husband and me). Both my parents are calling me selfish and jealous because my sister can have beautiful kids and I can't. AITAH for not contributing to my sister's kids' nanny?

ETA*: oh my goodness thank you for your kind words . My parents do help her with housework and childcare . 2 of her kids are highly special needs so she thinks with the new baby and current littlest ( she gave birth to the last one in December !) she needs more help and it’s my job to hire help ( indefinitely)

ETTA sorry I can’t answer all your questions I’m at work ( it’s my lunch time now lol). They are not overly religious. My sister said many time she loves being pregnant and newborn stage is her favourite. She said she is still not sure if they are done and she and BIL love big families . Thank you for the suggestion but I have zero interest in adopting my nieces or nephews. I have taken them out to events and water Parks , wonder lands ,and bought them gifts for birthdays and Christmas but I don’t want to adopt them We are French Canadian . We live in a small city near Quebec City . Yes my sister receives universal child care benefit from government for each kid , monthly

I'll give two:

Mockingjay (the third book in the Hunger Games series). It read like a dream sequence. And since it's purely from Katniss's point of view, we don't even really get a conclusion to the story and what happens to the government.

Ready Player One. The 80s references were fun and the tech was cool to read about, but I don't get the excitement in reading over and over again, "This would have been a difficult challenge for anyone else. Luckily, I've already memorized every single thing ever written or made in the 80s, so this was no trouble for me at all. No, you will not see me learn anything new that will help me in my quest. I will just already know everything and be able to figure everything out immediately." What kind of story is that?

I would nominate Wolf of Wall Street. None of the characters are likeable. They're all fucking monsters. Everyone in it is a great actor. But the movie is almost a masterpiece portraying these awful people.

Can y'all point to another movie that has the similar terrrrrrrrible characters but great actors?

I just can’t seem to get my head around it. I hate going to work, and once I’m there, I hate that too. It’s like all I have to look forward to is another 8 hours of work. It’s so draining. I tried looking up YouTube videos on what to do if I hate going to work, and I can’t find much. What do y’all do?

Edit: wow! So many responses. I def don’t have time to respond to them all now, but will try once my work day is over. I am feeling better about work, if that matters to anyone, maybe because it’s almost over for the day. Thank you everyone who came here and replied.
