ByeByeCry® comes equipped with a locking switch (the child lock!). More than likely, the machine is locked and that is why you can’t turn it on or off. Flip the switch to unlock the child lock and your buttons will work!

ByeByeCry® works best in close proximity to your baby. We recommend a distance of approximately 1-3 feet for the most effective results. Place within 1 foot for 1 minute and slowly move the device away from the baby, keeping within 3 feet. It’s important that the noise level is high enough to catch the baby’s attention. Allow them to interact with the sound. The goal of the sounds is to stop your baby’s fussiness and cries. Consult with your pediatrician if you have further questions or concerns about volume or the length of time you should be playing the device.

Both! You can set the timer for increments of 60 minutes or 120 minutes. If you don’t want to use the timer, simply allow it to play continuously!

The sound machine can run continuously for up to 16 hours, but because parents of babies with colic rely on our machine so often, we recommend charging it daily so you are never caught without it. Super-easy to charge Connect the USB to your car, laptop, outlet, etc. Charges to a full battery in 3 hours Pro Tip: If you use the sound machine overnight, charge it first thing in the morning so it's fully charged the next time you need it.

Use the + and - buttons to adjust the volume! Simply press the + button once to turn the volume up one level Press the - button once to turn the volume down one level

Press and hold the top right power button for 2-3 seconds. Do the same for shutting off the device.

Push the music note button to run through all of our peaceful sounds. Enjoy the calm with: Ocean, Fan, Shushing, Rain, and Classical

These sounds are soothing for infants because they mimic sounds a baby can hear in the womb. Since the womb is where a baby first develops self-soothing skills, it’s not surprising that when they hear a similar noise, it can have a calming effect. Babies in utero experience background noise ranging from 85 to 95 decibels. The sounds outside the womb can help distract a fussy baby and allow for soothing to begin.
