Afternoon Sitter Needed For 1 Child

Hi! I need a sitter for my son. He is 13 and has cerebral palsy. He walks and talks. He rides a special education bus and I need someone to get him off the bus in the afternoon and give him a snack. I also have an 11-year-old daughter but she is self sufficient and gets home a little after her brother does. We have one small 12 pound dog.
