Yes, you can leave the VAVA Baby Night Light plugged in, and it will still work so that you will not have to charge it night after night. However, we don’t recommend doing this for a few reasons:
Keeping it plugged in will hinder your kid from being able to carry it to the bathroom with them which may cause them to wet the bed.
Keeping it plugged in all the time will damage and eventually drain the battery.
Keeping it plugged in will consume more power, which will not save you in energy costs.
