Is this considered normal for a babysitter to do?

I am a SAHM that so happens to be a certified Early Childhood/Elementary/Special Ed teacher. I am also trained in SIDS/First Aid/CPR for Infants and Adults. I have 13+ years of classroom experience ranging from daycare to high school. I am presently babysitting 2 children in my home. In NC, a person can babysit up to 2 unrelated children in their home without being licensed. I am currently applying for my license and have a mentor Case Social Worker assigned to my home. She helps me document and everything. Well, I have a 18 month old little girl that is very picky about the food she eats. I supply both parents with an activities plan and menu. This mother has told me about the little girls being hungry when she gets home, she gets picked up at 6:30pm every day. Snack time is 3:30 every day. I change her and rub Desitin on her with every change. I am also potty training her. I wash and braid her hair once a week. Her mother doesn't like me sending dirty clothes home, so I have to wash them be fore placing them in hr diaper bag. I am trying to ween her from the bottle to cup. This little girl only eats veggies and fruits without spitting whatever out onto the floor. She cries every morning when her mom drops her off. Mom hints to me not taking the right care of her. If that is not enough, I also have a 4 month old little one that has a mom who wants me to text her pics every 2 hours or so. I also apply Desitin on him with every change. He is breast fed, but I have bottles for him. I have to place the bottles in a bowl of boiling water to warm up for his feeding. I also have to wash him with a washcloth, because she doesn't like wipes. I have had to supply my own bouncer, swing, play mat, and play yard with bassinet for him out of my own money. The sad part is that I only charge $85 a week per child. That includes meals and such. I am supposed to have tummy time with the 4 month old every day. I take them both for walks to the park. We hae a play set out back of our home and they play on that. I also have age appropriate toys or both children. If I am now just considered a babysitter, should I have to do all of this for $85 a week? Also, the mother of the 4 month old has asked me if I plan on taking on more children once I become licensed. She really only wanted me to watch her son only. Was she out of line for requesting that I not raise my rates and not take on more kids?
