3. Limit Screen Time
We know that screen time before bed negatively affects our sleep as adults by increasing the brain's electrical activity and decreasing the production of the sleep hormone melatonin, and the news isn't any better for kids. According to the Baby Sleep Site, kids who watch TV or play video games in the 90 minutes before bed get less sleep than those who don't. 

It's a good idea to set a "bedtime" for devices, preferably well before that of your child. If a nightly Sesame Street viewing is part of the bedtime routine, you may want to adjust it to an earlier time or phase it out altogether.
