Babysit

So i babysit for my sister in law and I’m starting to regret it but i need the money i gave her a discount because she as acting like everything was too much for her to pay as it is and it’s really starting to piss me off because she complains about everything like my nephew gets sick but he’s also not immune to being with they kids and i babysit other kids from time to time and she’s really making it seem like it’s my fault I’m just irritated like i clean home wipe down toys so everything to prevent it but kids are going to be kids , there’s only so much i can do and literally he’s the only one that is sick... ugh I’m so irritated i just needed to vent
