My niece is going on 7 months and I love her to death but every other week for several days straight my older sister drops her off for me and my mom to babysit. She has a job but I do as well and I get no choice if I even want to care for her. I am just expected to babysit during my days off without any pay for several hours. Its hard enough to deal with work, but I also have online classes to do. Is it wrong to say I don't want to care for her?
