Many children with autism, ADHD, or cerebral palsy struggle to fall asleep, which affects their mood, learning, and family well-being. Current sleep medicines like oral melatonin can be hard to swallow, have variable absorption, or cause fear of dependency. To solve this, we developed MMT Cream (Mother’s Melatonin Touch)—a gentle transdermal cream with 1 mg melatonin per gram, combined with soothing scents like lavender or vanilla. It is applied on the child’s chest, wrist, or feet during bedtime, allowing both calming touch and hormonal sleep support at the same time.This pilot study will include 15–20 children aged 3–10 years. For 2 weeks, we will observe their normal sleep (baseline), then give the cream daily for 4 weeks. Sleep onset time, total sleep, night awakenings, and parent satisfaction will be measured using actigraphy, sleep questionnaires, and diaries.
