What is the Weaning Feature and when should I use it?

The SNOO App is no longer available on the Google Play Store, and it will be removed from the Apple App Store on January 10, 2024. For an improved user experience, download the Happiest Baby App on iOS or Android.

SNOO's Weaning Feature prepares your baby for an easy transition to the cot.

During the first months, babies sleep better with the calming rhythms of the womb…for all naps/all nights. But by 5-6 months, most babies are developmentally ready to give up having their arms swaddled and gentle all-night rocking.

The SNOO App’s special Weaning option eases your child’s transition to a still cot when the time comes. When Weaning is on, your baby will still get soothing sound all night—but no motion.

There really is no rush to wean. Even if your baby’s toes touch the bottom of the bed, it is still advised that you wait until your baby is 5 to 6 months old to start Weaning.

It is best to first wean your baby’s arms from the swaddle by letting them through the SNOO sack armholes —and wait until your baby is sleeping well with the arms free—before you wean motion. (Click here to read our detailed advice on Weaning)

To turn on Weaning...

  1. Head over to the Setting icon at the bottom of your screen
  2. Under the Modes category, toggle on Weaning

When the Weaning is on, a W icon will show in the screen's upper right corner. Any previous baseline settings will be reset back to the blue baseline level.


Usually, within 1-2 weeks, babies get used to sleeping in a still bed and are ready to say “good-bye” to SNOO and transfer into a cot. And, if your baby fusses while the Weaning Feature is on, SNOO will respond with the usual boost in sound + motion. The rocking will continue for several minutes after the baby is calmed, then the motion will stop, but the sound will continue at baseline…all night long.

We advise using white noise for all naps and nights for at least 1-2 years…or longer. White noise becomes like a teddy bear of calming sound that can help toddlers and older children sleep better, even during transitions (like travel, illness, etc.).

Breastmilk is the best source of nutrition for babies. It is important that, in preparation for and during breastfeeding, mothers eat a healthy, balanced diet. Combined breast- and bottle-feeding in the first weeks of life may reduce the supply of a mother's breastmilk and reversing the decision not to breastfeed is difficult. If you do decide to use infant formula, you should follow instructions carefully.
