Do Magnesium Sprays Help Kids Sleep? What the Science Says


Are magnesium sprays the next miracle sleep cure—or just marketing?

You may have seen it on TikTok or in the parenting forums: magnesium sprays and lotions being hyped as the natural fix for kids who struggle with sleep.


As a pediatric sleep doctor, I get asked about these products all the time.

Here’s the truth about holiday travel and sleep: most of what you’re worrying about doesn’t matter. I get it. You’ve worked hard on your child’s sleep schedule. Maybe you just finished sleep training. Maybe you finally got consistent bedtimes working. And now you’re about to spend 3 days at Grandma’s house sharing a queen sized bed with a dog, a toddler, and a 14 month old who demands to exit the Pack N Play at 3am. You’re expecting disaster. But here’s what I’ve learned after 15 years of...

Hi everyone, Nap transitions are one of the most confusing parts of early childhood sleep. One week your baby is taking three predictable naps… and the next week everything is chaos. Naps get shorter, bedtimes get later, and suddenly you’re Googling “is my child dropping a nap??” at 3 AM. This week on The Sleep Edit, Arielle and I break down the messy reality of nap transitions — from 3→2 naps, 2→1 nap, and eventually the big one: dropping naps entirely.
