I have children before & after school. It varies as to which days they come, some do b/s only & other a/s only & a couple do both. Also some are term time only. I charge £5 per hour with a minimum of 1 hour per session even if they arrive after 8 and leave before 4.15.
I provide breakfast to a pair of siblings if they need it, they arrive between 7.15 & 7.30, a snack after school & an evening meal for those who want it, but they don't eat until 5 to 5.15 so is really only suitable for those who stay late.
Activity wise, I don't really plan but do occasionally have a specific craft item available for them to do if they wish, e.g. Christmas, Easter, Mother's or Father's Day. There is always lego, k-nex, puzzles, books and games available for them & they love being in the garden on my large climbing frame/playhouse & kicking a ball around.
I walk the children to & from school 97% of the time & use my minibus rarely for the school run, I think they need the walk to run off energy on wet play days and it gives us a chance to chat about their day at school, what they have done at home in the evenings/weekends.
The older children especially sometimes ask to use the computer to research information for their homework or to print something off, especially if they don't have ready access to a pc &/ printer at home, also they sometimes 'forget' to do their homework so panic in the morning that they haven't done or finished it & it is due in that day!
I start at 7.15 & finish most nights at 6, although last night was 6.45 due to snow & traffic jams. Also in the last three school days I have collected early twice from school, this is because on friday it shut at 11 am due to snow, Monday it was shut again because of snow & yesterday at noon due to a proper gas leak (not the French smell). Both times I have text around all my school parents to find out who needed their child collecting & have brought them home for collection by the parents when required, fortunately it hasn't taken me over my numbers and the parents have all been very grateful.
