My son's sleep patterns are pretty good. We start our bedtime routine around 20:30 - 21:00, and he's usually in bed by 21:30 (and asleep within minutes).
We have been planning our activities and schedule around that routine as a fairly hard deadline, even on vacations and other special occasions, for fear of causing lasting disruptions in his sleep schedule.
He's almost 3. What are the chances that a night of staying up late (for example, staying up an extra hour or two to enjoy holiday fireworks) would cause problems on subsequent nights (or mornings)?
What can we do to mitigate the disruption of such special occasions?
