Ensure you have adequate window coverings to block out sunlight during the day. Also consider other sources of light coming into the room such as the glare from a baby monitor or hall light coming under the door.
Keep all screens out of the child’s room. This means no iPads, TV’s, or smart phones. Artificial light exposure before bedtime stimulates a child’s brain and suppresses the release of Melatonin.
Try dimming the lights as you get them ready for bed. By darkening the room, you reduce the amount of stimulation around your child, which will help calm and settle them. A darkened room also tells your child that it’s time for rest.
