It's that time of year when it can be pretty easy to lose a couple hours of good sleep. Even if we're usually pretty good about keeping up with our regular bedtime routines, there can be a lot going on that can get in the way. Evening trips to the park or a late summer concert can keep us up later than usual. Uncomfortably warm bedrooms can make it harder to get to sleep and stay asleep. And the kids in our lives may feel summer coming to a close, bringing some extra energy and disrupted sleep in anticipation of a new school year.
