How you change with the second baby, an empirical study, part II: Bed time

I'm very strict with our kids' bed times and for both of them I have established night time routines pretty much from the day they were born.
With M it was: bath, pyjamas, milk, lullaby, sleep.
With B it is: pyjamas, milk, asking M not to turn the light on, telling M to turn the light back off, holding B in the dark room silently while attentively listening to the noises from the lounge and hoping he'll fall asleep before M gets bored of watching TV.
