Kids want candies all the time. And they can get up in the middle of the night, without you knowing it, and attack all the candy supplies. To avoid that, just put the candy inside a healthy snack empty bag. Your toddler will never check inside of it.
if your kid is scared at night and afraid of monsters, you can use a spray bottle to help. Just decorate it and fill it with water and say that it’s a very effective Anti-Monster spray and keep it in the night table.
