What is a wake window, and do I need one?

A wake window is how long a baby is awake between sleeps. The ranges online, including Cleveland Clinic's table, are rules of thumb that cite no studies, so treat them as a starting point and watch your own baby's sleepy signs. If sleep is worrying you, the AAP's tips and your pediatrician come first.
