Now, if you’re wondering whether or not you should have a nightlight on in your baby’s nursery, the answer is that it’s up to you. You might feel more comfortable having one on in there. Maybe the little bit of light makes your baby calmer or less anxious. Or maybe you like that it’s easier for you to sneak in and check on the baby with the nightlight on without disturbing him or her. If that’s the case, feel free to plug one in—it isn’t going to have a huge impact on your baby’s ability to sleep well at night. But keep in mind that not all babies are instinctively afraid of the dark. For Children Night lights can aid relaxation before bed, reduce fear of the dark in children, and provide lighting at night for better visibility.
