Me I turn the tables lol
I plan something they really want to do then just DON'T get ready, take ages to do anything etc. then by the time your ready you just say oh is that the time - not worth going now!!!!
and don't forget to keep reminding them all that you have to ask them hundreds of times to get raedy normally
Matthew got really bad at this so I told him we were going out to the local ball play area thing. Of course he was up and ready by 7am so I dragged my feet, didn't get hubby up until 10am etc and it was 11.30am by the time I was ready - so I just sat down and told him the play session finished at 12 so it wasn't worth going now and wasn't it annoying when people wouldn't get dressed when asked - he had a tantrum but I haven't had so many problems since!!!
That said I still have to nag senseless to get him completely dressed for school - he can start at 6am and still not be ready at 8.20am for pick up.... He'd happily go out with no shoes or coat even in the snow

I am lucky as he is picked up every morning at 8.25am by one of the teaching assistants, otherwise he'd never get there on time, sespecially now with baby to get ready too.
Of course we go out at the moment and hubby doesn't mention my hair is standing on end as I forgot to brush it

just what you need really!!
Matthew only has packed lunch with spoons etc in now because hubby does it before work - I was doing it as he was going out the door....
Oh and as I'm usually up between 4 and 5 it isn't lack of time....
