I’d start with LittleHippo Mella for a straightforward clock without an app, or Hatch Baby if you want phone controls, sound, and customizable light schedules. Groclock is another option if you like a visual countdown to morning.
We own a Hatch Rest+ 2nd Gen, which is now discontinued. The current models below are recommendations based on manufacturer information, not products I’ve personally tested.

What an Ok-to-Wake Clock Actually Does
An ok-to-wake clock, sometimes called a toddler sleep trainer, uses a light or picture to show when it’s time to get up. Your child doesn’t need to understand “6:45.” They just need to learn what the cue means.
With a color-based clock, that might be red for resting and green for morning. With Groclock, it’s a sleeping character that wakes up.
The goal is to make the routine easier to understand. The light can reinforce that routine, but it won’t create one by itself or guarantee your child sleeps later.
There’s also a useful distinction between a wake-up cue and an alarm. A silent color change can tell an already-awake toddler that morning has started. Adding sound can wake a sleeping child. Decide which job you want before setting it up.
Best No-App Pick: LittleHippo Mella
Mella would be my first look if the main problem is “my toddler doesn’t know when it’s morning.”
It uses sleeping and waking faces, with an optional yellow quiet-play period before the green wake signal. It also has a nap timer, sleep sounds, adjustable display brightness, and a child lock.
That covers a lot without adding another app to your phone. The trade-off is that you make changes on the clock itself.
One detail worth checking: Mella’s CR2032 battery preserves basic settings. It does not keep the light and sound running when the power goes out. The clock still needs its power cable.
For a family that already has a sound machine and mainly wants a clear morning cue, this is the option I’d compare first.
See Mella’s features and current price at LittleHippo.
Best for App Control: Hatch Baby
Hatch makes more sense if you want to adjust the light and sound from your phone or build different schedules for bedtime, naps, and mornings.
Its schedule options include Time-to-Rise, Time-for-Bed, and custom sound/light schedules. You can choose a quiet light cue or include sound when you actually want a wake-up.
Hatch Baby includes three months of Hatch+. After that, the subscription is optional: basic lights, sounds, and bedtime/wake cues remain available without it. The paid extras include additional content and sleep-support features, as explained in Hatch’s purchase guide.
The main drawback for our house is power. Hatch Baby has no battery backup. We get enough outages that I’d factor that into the purchase. It also uses Wi-Fi for setup, and Hatch recommends a stable connection for reliable scheduling.
I’d consider it if the phone controls and flexible routines will get regular use. If you mainly want a face that changes at breakfast time, Mella gives you a simpler starting point.

Another No-App Option: Tommee Tippee Groclock
Groclock’s appeal is the countdown. On the Ollie the Owl version, stars disappear as wake-up time approaches, then the sleeping owl wakes up. That gives a child something to watch beyond a light that suddenly changes color.
There are two saved wake-time modes: nighttime and daytime nap. You select the mode you want; this isn’t an automatic weekday/weekend calendar. The Ollie instruction manual also specifies that sleep mode must be activated each time you use it.
The USB-powered model has adjustable brightness, an optional digital clock display, and an optional audible alarm. A button lock helps keep settings from becoming a toddler project.
Its power limitation is worth knowing: Tommee Tippee says the clock pauses during an outage. After a longer interruption, you’ll need to correct the time.
I’d consider Groclock if you particularly like the visual countdown and don’t mind the extra bedtime button press. Check the exact model when shopping, since older versions use different pictures.

How We Use Ours
Our Hatch Rest+ sits in our son’s room, mainly as a dim overnight nightlight and a light-and-sound cue for ending naps. When we use white noise in the room, it stays very low. The Dohm outside his door handles household-noise masking.
That’s why I like having light and sound controlled separately. Sometimes I want a little glow. Sometimes I want to signal that the nap is over. I don’t need every feature running at once.
Hatch no longer makes or sells our Rest+ 2nd Gen. If you already own a working one, check its scheduling features before buying a separate toddler clock. You may already have what you need.
I’ve covered the rest of our setup in Hatch vs. Dohm.
What Age Should You Start?
Check the guidance for the model you choose. LittleHippo recommends Mella’s sleep-trainer function from around age two, when children are starting to learn colors. That’s a product recommendation, not a deadline every toddler has to meet.
I’d focus on whether you can practice a simple cue together. Show them the resting light, then the morning light, and explain what each means. Understanding the color and reliably waiting for it are separate accomplishments.
If it isn’t clicking yet, you can keep the explanation simple and try again later. There’s no prize for being the youngest person in the family to obey a lamp.
Setting It Up Without Making Bedtime More Complicated
- Choose one clear rule. Decide whether the cue means “you can get out of bed,” “you can leave your room,” or “it’s time for us to start the day.” Use the same explanation each time.
- Practice while everyone is awake. Set a short demonstration so your child can watch the change. That’s an easier time to explain it than the moment you’ve been pulled out of sleep.
- Start with a manageable expectation. I wouldn’t introduce the clock and immediately expect a much later morning. Give your child a chance to learn the cue before asking more of it.
- Check visibility and brightness from the bed. The cue needs to be visible without lighting up the whole room. Keep the device and its cord out of reach, following the product instructions.
- Decide whether sound belongs in the routine. For an “okay to get up” cue, start by considering light alone. For ending a nap, you may want sound too.
- Respond to your child’s needs. Needing the bathroom, feeling unwell, or being frightened doesn’t have to wait for green. The clock should make the routine clearer for both of you.
Ok-to-Wake Clock FAQ
Will an ok-to-wake clock stop early waking?
It can give an awake child a consistent signal for when the day starts, but it doesn’t guarantee more sleep. I’d buy one for a clearer routine, with realistic expectations about how much practice it might take.
Do I need another clock if I already have a Hatch?
Possibly not. Check your model’s light-scheduling or Time-to-Rise features first. Our Rest+ already gives us light and wake-up controls, so a second device would need to solve a different problem to earn space on the dresser.
Is an app necessary?
No. Mella and the non-connected Groclock let you set their cues on the device. Hatch Baby is the choice here for parents who want app control. Think about how you’ll actually use it: occasional changes at the dresser, or adjustments from elsewhere in the house.
Which One Would I Choose?
For a straightforward toddler wake-up clock, Mella would be my first look. For phone controls and flexible sound-and-light routines, I’d consider Hatch Baby. Groclock is worth comparing if the visual countdown appeals to you and you’re comfortable activating it at bedtime.
If you already own a working Hatch with the right features, I’d try that first. Toddlers generate enough shopping lists on their own.
