A few little questions.
Should I follow the sample exactly?
Use it as a flexible example, while following cues and the pediatrician.
Can this explain every night waking?
A timetable cannot diagnose hunger, illness or the cause of a change.
Do safe-sleep rules change with the routine?
Infant safe-sleep guidance applies to naps and night sleep, including during travel or daycare.
Where can I adjust our example day?
Use the schedule generator with the actual age, wake time and available nap options.
