Light in the Dark
 
      Since we will not turn off the lights casually, leading to global warming, this night light does not require you to spend time turning off the lights, because you only need to turn on the lights, and the night light will automatically turn off, saving a lot of electricity. You can also put the night light next to the baby so he can learn how to sleep and not be afraid of the dark anymore.
