Before And Afterschool Childcare For 13, 11, And 9 Year Old Children

I am a single working mother who is looking for early morning care to ensure my children get up and on the bus and then afternoon care for a short period of time when they get home from school. The morning hours would likely be from 6 a.m. -8 a.m. and entail getting the kids up and making sure they have breakfast and get on the bus. Would like someone who has a car and can take kids to school if bus doesn't come or they miss the bus. I have a 50 pound, very friendly dog, so needs to be comfortable with that and bonus if able to walk him on occasion. In the afternoon, I would like someone to be there when my youngest gets off the bus and to help the kids get started on homework before I get home (generally around 4:30-5pm). Reliability is very important to me. This would be every other week since sharing custody with their father.
