Luckily we've got a team thing going on here, but there have been nights where one of us has to do the lot ourselves..

Our routine (when running solo) is :

Everyone eats together - usually around 6-6.30pm.
While DS is still in his highchair finishing off dinner, i go & run the bath and get jammies ready.
I turn on the heater, turn off the lights and set the iPod going with sleepytime music.
Then I come back in and make very warm bottles which sit on the lounge until he's finished in the bath.
Then after bath, get him dressed and give bottles.
Then it's straight into bed.

He's usually ok in the bath by himself now for short periods, so nowadays I can get the jammies and bottles ready while he's in the bath.

HTH a bit!
