WOW....You are one extra nice person. I have been taking care of 6 children in my home for 25+ years.Granted they are younger but still you should not feel taking money to have this child all day is not warrented. You are keeping her safe and out of trouble.Why are you responsible for breakfast? All my children arrive for the day haven eaten a breakfast at home. They arrive as early as 7:30 am.I offer a breakfast snack at 9:30 am -milk toast or muffin and a piece of fruit. Lunch is milk bread protien and fruit and veg. another snack at 3:30. Unless the parents were paying you a lot you should be able to have the girl bring her lunch and have eaten her breakfast home.Taking care of other peoples children is hard but both parents are making a decent amount of money and have piece of mind that there daughter is safe.When I first started this bussiness I made a lot of mistakes -choices that cost me money but over time it works out.Good luck.
