I've done it but primarily because the hours were good, and the pay is a nice extra! The bus stop is now at the end of my laneway for one school, but only a 2-5 min walk (depending on who I have that day) for the other school. Hours for me are 8:40 a.m. and 4 p.m., so I don't have to worry about naps at all.

I charge $20/day/child OR $15 for either morn or afternoon/child/day. I have the kid for 2 hours max.

One other thing you'll have to consider: Do you want these kids on P.D.Days/summer, etc? I don't provide full day care at the moment.
