Why is sleep so important anyway?

We all know how amazing a good night’s sleep feels—waking up refreshed, energized, and ready to take on the day. But sleep isn’t just about feeling well-rested; it’s a key pillar of overall health, affecting everything from brain function to metabolism.

For adults, sleep helps us stay sharp, make good decisions, and maintain our physical and mental well-being. But for children, sleep is even more critical. Their bodies and brains are growing at an incredible rate, and quality sleep is essential for healthy development.

Despite its importance, many children simply aren’t getting enough rest. Research suggests that 20–40% of children don’t get sufficient sleep, with over 2 million kids in the U.S. suffering from sleep disorders and 20–30% of young children worldwide struggling with sleep issues. The recommended amount? 10–12 hours per night—but as any tired parent knows, that’s often easier said than done.

Newborns experience rapid growth in their first year—physically, mentally, and emotionally. Their brains are busy forming new connections, their bodies are developing, and their emotions are being shaped through interactions with caregivers. Sleep is a huge factor in all of this, helping to regulate emotions, support learning, and promote overall development.

And here’s something important: how parents and caregivers respond to their baby’s sleep (or lack of it) can make a big difference. Babies rely on us to help them learn healthy sleep habits, and the way we support them during wakeful nights can impact their ability to settle and sleep longer stretches.

Beyond just feeling tired, lack of sleep can affect so many aspects of life. Poor sleep has been linked to difficulties with decision-making, increased cravings for unhealthy foods, and even metabolic imbalances that affect body fat and insulin levels. Even one night of poor sleep can throw things off!

The good news? Sleep habits can be improved with the right guidance and support. Small changes can lead to big improvements, helping both children and parents get the rest they need.
