Although not a single parent, I have dd1 go to gymnastics with a school friend - so the dad does school pick up and drops the girls off. I then pick up at 6 and bring them home. I would ask around to see if anyone lose is doing it?

Another day I start work early and finish early so I can do the pick up and take the girls swimming. Our pool has classes that go until 7pm so there's always a later option if we need to have weekday classes after work.
