Are toddlers scared of the dark? My 18 month old sleeps alone in his room. Should I be leaving the light on?

My boys are okay in the dark. They know that once its dark its time to sleep. You can leave a night light on if thats what would ease him and let him sleep.

yes some toddlers are afraid in dark, but if you always turn off light before bed and make it routine then it will not be a problem.

If your toddler isn't making a ruckus about it, it should be fine.
