Trouble with sleep is a common side effect of ADHD medications (which are stimulants). To be sure your child can wind down at bedtime, ask their doctor about changing the dose, the timing of it, or the type of medication they’re taking. There are non-stimulant options that could work for your child’s ADHD. It may take a few tries to find the combo that works best for focusing during the day and going to sleep at night.
You may have most of the lights off in your child’s room at bedtime, but does that make the room dark enough? Your kid’s body clock may need more of a nudge to know it’s nighttime. Unplug or cover any electronics that glow. Blackout curtains can help shut out extra light from outside. If your child will wear it, a sleep mask can also do the trick.
