Yes, you can keep the bounce always on through the Cradlewise app (available for both iOS and Android).
Navigate to Settings > Crib > Bounce, and set the “Always on bounce” as ON. This will continue to bounce the cradle even after your baby starts sleeping soundly.
If the bounce mode is set to “Auto”, the cradle will bounce with a “super gentle” amplitude once your baby goes to sleep. In ‘Super gentle bounce,’ the crib has minimum bounce. The bounce amplitude will not go higher than the minimum in this setting, even after the baby stirs/wakes up.
