This is going to be a long story but please read and comment . thank you ladies

First let me explain I am 19 weeks pregnant, and starting to really pop lol.

My boyfriends mother has 3 kids who are 2,5,&9 years old.

His sister has 2 who are 3&5years old.

Recently his sister got into some legal trouble and her mother and her have to go to the lawyers almost every day.

The past three days I have had to watch all of the kids by myself from 11-7 (no pay)

The older kids are a bit easier because they only argue, the younger kids (2&3) fight all day long the pull each others hair, bite, hit and kick. I literally have to pull them apart. When I pull one off the other they start screaming and crying and kicking so I have to pick then up and carry them to the couch then go back for the other one.

This happens multiple times a day.

Not to mention they are pretty heavy for there age.

The older three are pretty good but they do have there moments where all they do is scream and eachother. I used to be able to handle all this but now I just can't. It hurts to pick up the younger kids, my heart races and starts hurting, my blood pressure goes up. I get so mad because no matter what I say or do none of them listen to me . there moms tell me all the time to spank them or use a paddle on them, and I've seen them do it multiple times , all I do is pop them on the booty but it doesn't help.

I have watched them all for the past three days , I feel so drained , and I'm always aggravated when me and my boyfriend do go home.

I have raised two girls before but they had a strict mom(when she was around) so they listened. They still argued and had tantrums but not as bad as these kids , so Its not because I don't have experience , I have a ton.

I just don't know what to do because I can't keep doing this. I feel like I'm going crazy.

Is it just me? What do y'all think?
