Try listening to the sleep story instead of watching it. If you turn off your phone 1 hour before bed you’ll tend to sleep better and fall asleep faster. This is why when you look at a bright light, even if you have your device on night mode, you will get that blue, purple, or green light affect when you close your eyes! This keeps your brain awake at night. So turning your phone off 1 hour before bed, erases all the after affect of the lights which makes your brain ready for sleep!
