I have been doing this on and off since I was 16 and I love it! I worked 4 days a week for a single mother, taking care of her kids from 1:30 until she was off work. I picked them up from school and I also made sure they ate and did homework, etc. Ages of the kids I have watched are 4 and 6 but I am willing to watch any age.
