H.W.
We are in bed, ready to read stories at 7. (We start pjs, teeth brushing/face washing around 6:30; earlier if his room needs a pick-up or if I can just see we'll need more time. ) By 7:30 I'm usually saying goodnight.
We stick to this schedule because he's five and needs about 11 hours of sleep. We don't nap. We'll keep to it during summertime, too, but I'm more flexible if there's something special (outings, events, camping-- I let him stay up much later) going on.
