Expert Reviews

What experts liked

It has a built-in sound machine with three settings (rain, white noise, and ocean), a nightlight with five colors, a countdown timer for naps and time-outs, and comes in one of four colors.
MELLA also includes three alert sounds and both an alert and silent countdown for timed tasks for older kids.
It has an appealing face that changes expressions to let kids know when it’s time to get going or wind down.
This night light serves two very important functions: it gives little ones a sense of security when it’s dark out and helps keep them in bed until a (semi) reasonable hour.
The happy face closes its eyes when it’s time to go to sleep. It also has a digital clock display, a built-in sound machine, a night light with five colors and a nap timer.
Coming in a playful spherical design, this clock features three sleep sound options namely white noise, ocean and lullaby to gradually put your child to sleep and you can also choose from three alarm sounds which are child friendly waking up alarm sound.
MELLA also features three sleep sound options and five night light colors to soothe your child to sleep. MELLA also features three alarm sounds and both an alarm and silent countdown for timed activities for older children.
It is possible to keep your children in bed longer and attain more sleep. Basically, MELLA utilizes colors and easy to understand facial expressions to impart the kids about bedtime and wake-up time.
Mella’s night light is a nice feature with several different colors you can choose from amber, Green, Blue/Green, and White. You can set the night light to glow for 10 minutes up to 90 minutes or continuously glow throughout the night.
This adorable designed clock isn't just your typical kids alarm clock, it can also be used features a sound machine, night light and nap timer (that can be used for time out!)
It’s certainly not unique, but it’s nothing short of an awesome feature to help your kids take the clock a little more seriously. However, the execution is what matters here, and the graded LED ring around the inner facing goes a long way toward making this worth the price.
The MELLA is an adorable sleep trainer clock, with a happy little smile, that has a lot of other functions that I care less about because the sleep trainer function is worth its weight in gold.

What experts didn't like

The sound coming from the machine could be improved. To us, it sounds like static noise using all three settings.
I think that the time could be larger – it’s hard for me to see from far away. Or at the very least, I’d like an option to have the time read larger for when the kids outgrow the sleep-trainer-smiley-face function.

She has spent the last eight years working as the marketing director for Charlie’s Kids Foundation, a nonprofit that aims to educate families about SIDS and safe sleep. In that role, she travels around the country learning and educating caregivers and providers on the latest and greatest safe-sleep information to prevent infant death.

As mom to two elementary-aged daughters, she spends hours researching the best and safest products for her own kids. She is quick to get in the weeds with other mamas, and uses humor to cope with parenting woes from potty-training to teaching kids to read.


Sleep is so important for a child’s growth and development, but curious little ones don’t always want to go to sleep for fear of missing out on something older siblings or adults are doing. Alarm clocks are an excellent tool for teaching kids when they need to go to bed and when they need to wake up.

Alarm clocks are just one part of the often-humorous sleep timeline when it comes to kids, says our parenting and safe-sleep expert Kate Desmond.

“You spend the first several years of your child’s life trying to get them to go to sleep,” she says. “You then spend the next several years trying to get them to stay in their bed until it is an appropriate time (read: actual daytime) to get up. Finally, you graduate to the other side of the sleep rainbow in which you are begging them to get up with threats of ‘you’re going to be late’ and bribes of ‘Captain Crunch is downstairs.'”

When shopping for a child’s alarm clock, you’ll want to keep your child’s habits and age in mind.

Look for an alarm clock design that appeals to your child. There are models that remain simple and have a traditional look, units that are created in the shape of a friendly creature and clocks that come in the shape of a highly recognizable children’s toy, such as a Lego brick.

Select an alarm clock that has a built-in night light if your child is still a little afraid of the dark. This will give the child a sense of security so that they are able to stay in bed until it’s time to start a new day. Some clocks even come with a choice of night light colors, which is nice if your child has developed a favorite color.

“The best alarm clocks for toddlers have features like a built-in sound machine and nightlight,” Desmond says. “Bonus points if that light has multiple color options and a color indicator that tells them when it is time to sleep and when it is time to get up.”

Some kid alarm clocks turn green just like a traffic light to let kids know it’s okay to get up and start the day. This helps deter children from waking mom and dad up in the middle of the night.

Use an alarm clock that provides a little noise for children who can’t fall asleep in total quiet. The LittleHippo Mella Ready to Rise Children’s Alarm Clock has a built-in sound machine with three different settings to choose from. Little ones can pick from the rain, white noise or ocean settings, which will run softly in the background.

Keep your eye out for an alarm clock model that has a snooze button for older children and teens. Some models have a nine-minute snooze that gives kids a little more time to wipe the sleep out of their eyes and mentally prepare to start a new day.

Look for any extras that one model may have over another. Some kid alarm clocks have a countdown timer for naps and time-outs, while others have animated faces that open their eyes when it’s time to rise and shine and shut their eyes when it’s time to sleep.

Older children may also appreciate a multi-functional alarm clock, says Desmond.

“For older kids, look for features like Bluetooth to stream their devices so they can wake up to their favorite tunes. Some even have USB ports to charge other electronics,” she says.
