Welcome to The Sleep Edit, the podcast that helps tired kids and parents sleep better. Each week, Dr. Craig Canapari and sleep consultant Arielle Greenleaf break down evidence-based strategies you can actually use.

Why are nap transitions so confusing—and why do they so often derail nights? In Part 2 of our napping series, Craig and Arielle dig into the real-world challenges families face when moving from 3→2 naps, 2→1 nap, and eventually dropping naps entirely. Using concrete examples, sleep-need math, and practical troubleshooting, this episode explains exactly what to look for and how to navigate every transition with less stress.

• How to know when it’s time to drop a nap

• The signs of a nap transition vs. a temporary “nap strike”

• Why total 24-hour sleep matters more than wake-window charts

• What typical daytime sleep looks like for infants and toddlers

• The sleep math behind transitions (high vs. low sleep-need kids)

• How daycare schedules can derail naps—and what parents can control

• Strategies for capping naps, shifting schedules, and preventing bedtime battles

• When early morning awakenings actually signal too much daytime sleep

Why do some toddlers nap like champs while others refuse entirely? In Part 1 of our Napping Spectacular, Craig and Arielle unpack what the science says about total sleep needs, how nap patterns change across infancy and early childhood, and the very real “art” of troubleshooting naps at home. We cover when to drop naps, how brain development (especially the hippocampus) affects nap transitions, what to do about short naps, and how to keep daytime sleep from stealing restorative overnight sleep. We also talk through safe approaches to contact naps and why it’s normal for newborns to have unpredictable naps and periods of crying.

In this episode of 'The Sleep Edit', we dig into the topic of sleep supplements for children, specifically focusing on melatonin and magnesium. Melatonin and magnesium (and "calm" and "sleep" gummies in general) have become very popular among tired parents, but what is the actual evidence for these supplements? Are they safe? What do parents need to know?

Holidays can be a time of joy, family, and fun—but they can also throw a wrench into your child’s sleep routine. Whether it’s late-night celebrations, travel to visit relatives, or adjusting to time zone changes, holiday sleep disruptions are a challenge for many parents. But don’t worry—we’ve got you covered.

In this episode of The Sleep Edit, Arielle Greenleaf and Dr. Craig Canapari discuss practical strategies for navigating holiday sleep challenges for children of all ages. From tips for maintaining flexibility while traveling, to handling sugar-fueled energy spikes and keeping routines intact, this conversation is packed with actionable advice to help your family enjoy the season while staying (relatively) well-rested. They’ll even share some pro tips, like the ultimate New Year’s Eve bedtime trick you won’t want to miss.

Remember: holiday sleep doesn’t have to be perfect—it just has to work for you and your family. So, give yourself some grace, enjoy the cookies, and focus on the quality of your time together.

In this episode of the Sleep Edit podcast, we welcome Dr. Shelby Harris, a leading expert in behavioral sleep medicine. Often, parents are struggling even after their kid's sleep problems are addressed. We talk about the common sleep challenges faced by parents focusing on the impact of stress, hormonal changes, and modern technology on sleep quality. Dr. Harris provides insights into the diagnosis and treatment of insomnia, emphasizing cognitive behavioral therapy for insomnia (CBTI) and its effectiveness over medication for long-term improvement. The conversation also explores the practicalities of sleep hygiene, sleep restriction, and the influence of consumer sleep tracking technologies.

In this episode of the Sleep Edit, Craig and Arielle are thrilled to welcome Dr. Sujay Kansagra of Duke University to discuss the weird and wonderful world of parasomnias, restless leg syndrome, and restless sleep disorder in children. Parasomnias include NREM parasomnias (sleep walking, hypnic jerks, night terrors) and REM parasomnias (sleep paralysis and nightmares).

Today, Craig and Arielle unpack the often mystifying world of newborn sleep—those crucial first three months. The inspiration for this episode was Craig's new niece, who was 2 weeks old at the time of recording. Whether you're navigating the unpredictable waters of infant sleep or just curious about what's normal, this episode promises to arm you with the insights you need to feel a bit more in control—or at least to understand that sometimes, chaos is just part of the parenting package.
