Advice?

Okay let me begin with I do not mind babysitting I love the extra money and love kids but I have my own 2 kids ( 2 year old and 7 months old) and I babysit a 10 month old for a high school friend I’m at SAHM and recently she just been real bossy and irratating. My baby girl was puking non stop and I told her listen I can’t babysit Tomo my daughter been up all night and she messaged back saying you half to blah blah I have no choice like I choose to babysit your child and than the other day she like you half to watch her wendsday but I don’t work I going to get a tattoo but I’ll pay you some let me start by 8 hours I charge 30 an less is 25 which in my eyes is cheap espically when she doesn’t displain her child and it gets into everything yes I know she a baby I understand but My kids don’t get into things like she climbs on my tv stand an rips stuff down I tell her no I don’t spank I don’t like to spank or tap there hands makes me feel bad but like she got into my Christmas decorations I had up and her mom just laughed like NO she can not touch my stuff like that my own kids know better but my point is she brags about spending 70 on nails 80 on makeup An now she bragging about her 250$ tattoo she getting but when I asked to get paid more she got all mad An saying she needs to save money MIND you she lives at home with her parents and has a cheap car so she has no bills besides her kid which I know kids are expensive some times but seriously I need to focus on my kids I have to focus on her kid more so she doesn’t get hurt or eat anything which she has broken my swing which I had to pay 95$ to get a new one An her mom laughed An said ya she likes wires like wtf but I don’t get how she can tell me when I half to watch her kid my husband told me no cause 3 times a week is enough and she jist using me because her parents wont be kid like listen I don’t get to do anything I don’t have someone to watch my kids so I can enjoy my life you know An honestly idc to cause my kids are my life idk I’m just really irratated about everything sorry about this rant 🤦🏼‍♀️ but how would you feel
