Tell you what, Mars, here's my expected bedtime routine, and what really happens.
7.30 Kids upstairs to undress, into bathroom, brush teeth, wash hands and faces, then into bed, read for 10 minutes, lights off, settle go to sleep.
7.30
Send kids upstairs, after much prevaricating, lots of "where's my .....", Muuuuuuuum, he/she is being mean to me", "he/she pinched me" they eventually stip off, put pyjamas on, leaving clothes where they fall. Tell them to put clothes into basket, which takes around 10 minutes.
7.50, kids still in bathroom, much screeching, giggling and jumping about (which rattles a light fitting in the front room, driving me nuts), go upstairs, find that the toothpaste has somehow magically adhered itself to almost every surface, including on bodies and pyjamas of small people, water has magically appeared on the floor, and towels are everywhere. Force aforementioned small people to actually brush teeth and wash, and make them clear up mess.
8pm, get them in bed, settle them with a book and say goodnight.
8.02pm, shout up the stairs for them to get back into bed and stop messing about.
8.04pm, shout up again, and warn that I will come up if I have to shout again.
8.10pm, go upstairs, tell off two small boys who are out of bed and messing around.
8.12pm, hear DD screeching "SHUT UP!!!" at the boys, shout upstairs again.
From 8.13 to 9pm, go up and down the stairs, threatening kids with dire things if they don't settle down and go to sleep. Take 10p away from each of their pocket money with the promise that they can earn it back if they do 3 nights in a row without messing about.
9.15, kids finally asleep and mummy pours herself a large glass of wine.
