My(25F) sister (15F) made a baby bump

Im 25 years old.<br><br>So, I am a part-time babysitter for my sister(15F) who was unexpectedly pregnant by my brother in law(25M). I don't know if anyone else has a sister like this but she is very manipulative. She is making my brother in law and me do all the chores and everything. She doesn't help with anything at all. She just complains about her back and sits on the couch all day doing nothing. She is making my brother in law do all of the cooking and cleaning and even made him get a second job to pay for the baby. But the thing is he is already providing her with everything she needs, so I don't understand.<br><br>She is already on the government assistance program and he is giving her $1000 every month. She has everything she could possibly need for the baby. My brother in law is stressed out.<br><br>So, I got a part-time babysitting job for my sister (who is 8 months pregnant) for 40 hours a week. She doesn't have a license.<br><br>I do the following things:<br><br>1) I clean her apartment. She is messy, so I need to constantly clean up after her.<br><br>2) I shop for her groceries, do the cooking, and do the washing. She doesn't have a license and can't drive. She is also supposed to be resting for the baby.<br><br>I do the dishes and everything.<br><br>3) I help her bathe and get dressed.<br><br>4) I entertain her. She wants me to constantly be around her.<br><br>5) I drive for her.<br><br>So, I am doing all the above things and my bro in law does all the yard work, fixes things around the house, pays for everything, and does everything else. We both do the laundry.<br><br>I work full time as well, so I am also doing my full-time job and my part-time job.<br><br>I am getting really tired of this. I am tired to the point where I don't even want to visit my family anymore. I'm angry that my sister is making my bro in law work a second job. He is already tired enough. He is also getting really angry and I am worried that he will fight my sister.<br><br>I just want to know what to do. Can I talk to my sister about this? She is very difficult to talk to.<br><br>I don't want to upset my brother in law or make him angry because he is also tired. But I also don't want to enable my sister.<br><br>Can anyone give me advice? I don't know what to do. I'm tired.<br><br>Tldr; sister is making my bro in law and I do all the work and my bro in law is getting really angry. Idk what to do.<br><br>Edit: I don't have a job for my sister. I am a babysitter for kids. Sorry for the confusion. I also don't live with my sister. I live in a different state. I just come to visit and help my sister out. Also, no one knew she was pregnant. We were all shocked when she announced it. I have no idea who the father is. She won't tell us.
