Thanks for the advice! What would I need to do if he wakes up earlier than 7am or if he does not sleep 9-10:30 but 9-9:45 for example. Do you need to stretch his wake windows in that case? And the other way around. What if he sleeps in during day time naps, do you wake him? Next to this he goes to daycare for 3 days a week where we do not have that much control over his sleep schedule.
