SweetSpot®: Your smart sleep timing companion
Updated Jan 05, 2026

Figuring out when your baby is ready for sleep next involves more mental math than most people realize. You're tracking wake windows, watching for cues, and trying to catch that narrow window between "not tired enough" and "overtired." It's a lot to keep track of, especially when you're already doing so many other things.
That's why we built SweetSpot, a tool in the Huckleberry app that predicts when your baby will be ready for sleep next, so you can reduce the mental math and let us do the heavy lifting for you.
What is SweetSpot?
SweetSpot is Huckleberry's smart sleep timing feature that predicts when your baby is likely ready for sleep. Think of it like a personalized sleep forecast! SweetSpot starts with age-appropriate wake windows, then adjusts predictions based on your child's actual tracked patterns.
After logging sleep in the app, SweetSpot® starts delivering predictions that take the guesswork out of timing. The more you track, the smarter it gets, continuously refining its predictions as your baby's needs and patterns evolve while they’re following a “schedule” based on wake windows.
You'll see SweetSpot predictions right in the app, and you can set up notifications to alert you before the next sleep window arrives. iOS users can also view predictions on their lock screen through Live Activities, so you always know when naptime is approaching without opening the app.
SweetSpot is available starting at 2 months old, when natural sleep patterns begin emerging from the unpredictability of the newborn phase. It's designed to work alongside your parental instincts, not replace them. It’s still important to factor in your baby's cues and quirks! However, with this tool, you can spend less time keeping your eye on the clock.
Why parents love SweetSpot
It eliminates nap math
If your baby is on a wake window-based schedule, SweetSpot can remove the need for you to remember exactly when your baby woke up from their last nap while you're juggling everything else. The tool does the timing work for you, predicting when they will be ready for sleep based on your last logged sleep (the more you log, the more refined the tool becomes). You get a clear estimate instead of having to do constant guesswork.
It makes your day plannable
Wondering if you have time for that Target run? SweetSpot helps you plan ahead. When you know when to expect sleep, this can help you build your day around it. Plan errands, schedule coffee dates, and coordinate with caregivers, knowing when the next nap window is expected.
It keeps everyone on the same page
When grandparents, partners, or other caregivers are watching your baby, they can follow the same predictions — no more texting back and forth about when naptime should be. (Now, whether they follow the plan is a whole different story!) In theory, everyone stays aligned, which can help support more consistent sleep no matter who's on duty.

What makes SweetSpot different
Personalized to your little one
SweetSpot analyzes your child’s logged naps and bedtime (from a minimum of one logged sleep) to provide customized guidance on when they may be ready for sleep next.
Used by millions of families
We were the first to bring predictive sleep timing to parents, and we've been refining this technology longer than anyone, allowing us to deliver remarkably accurate predictions. Millions of parents have used the tool! Many say it feels like magic.
Built to enhance your instincts, not replace them
SweetSpot handles the math and the timing. But you're still the expert on your baby. The feature is designed to work with you, giving you data-backed confidence while you do what only you can do: know your child and respond to their needs. We’re here to support you, so you can support your little one’s sleep needs without all the calculations and clock-watching.
How SweetSpot works
Step 1: Track sleep
Start by logging one sleep in the Huckleberry app. When you consistently track, predictions become more personalized and precise over time.
Step 2: Get your predictions
SweetSpot displays when your baby will be tired next, which can help make falling asleep and staying asleep easier. You can also set up notifications to alert you a certain number of minutes before the predicted time, giving you a heads-up to start your wind-down routine.
Step 3: Plan around the timing
Use the predictions to structure your day. You'll know whether there's time for an outing, when to start the nap routine, and how to coordinate with other caregivers.
Step 4: Watch it get smarter
While your baby is following a wake window-based schedule, as you continue tracking, SweetSpot refines its predictions based on your baby's evolving patterns. It adjusts as your child grows and sleep needs change, helping support their sleep needs and giving you a break from the guesswork too.
