I have 3 dcs two boys (7 and 5) and dd who is nearly 9 months.
First thing I do is make sure I've fed dd and changed her nappy just before I go to fetch the boys so that she is happy and comfortable.
At the school I have to pick up ds2 from the infants first, then go round to pick up ds1 from the juniors, then send ds1 back inside at least 3 times to fetch the things he's forgotton.
When we get home the boys have to take their shoes and coats off and put them away, then put their lunchboxes by the sink.
Next its upstairs to change out of their uniforms while I prepare a drink and snack for them, followed by giving me any letters etc they have in their bags. I read the letters and fill in any forms or reply slips while they eat their snacks, then they stay at the table to do their homework and I sit with them to help.
After written homeworks we all snuggle up on the sofa with dd and they take turns to read their school reading books to us all.
Finally, ds1 always says "can I have my nintendo time now?" and I say yes they can go and play (assuming he hasn't forfeited nintendo time by commiting some heanous crime - usually picking on his brother or answering back). BadPoet I do the whole going on the computer/nintendo is a huge favour - whilst secretly wanting them to disappear to their room for a while routine as well.
Ds1 has half an hour on the nintendo and then 'helps' ds2 have his half an hour on the pc. Then they play until tea is ready.
I get half an hour to MN drink a coffee and play with dd, before I start the tea.
Dh gets home just as tea is ready, we eat together and then dh does the boys' bedtime routine as he doesn't get enough time with them otherwise.
