I would do everything possible to make after school care no more than 2 days a week. Obviously this may not be possible but be as creative as you can and try and get your employer on side. My kids get picked up by a neighbour once a week at the moment - could you pay one of his class mates parents to care for him or to take him to an activity all the kids do? When I have to use after school care and during holidays I use a sports based centre that employs education students who have the energy to play soccer and slide down hills on cardboard. That way they get plenty of fresh air and exercise.
