When I took my initial deep dive into the infant sleep world, I quickly stumbled upon the term, wake windows.  Wake windows are everywhere.  Perhaps you’ve already heard of them yourself.  If you haven’t, wake windows refer to the amount of awake time your little one has in between sleep periods.  So, everything in between like diaper changes, feedings, tummy time, walks, and nap and bedtime routine counts as awake time.   But what isn’t commonly talked about is that wake windows have an expiration date.
