Baby Sleep Trainer is designed to help parents train their babies to sleep through the night using a proven method that teaches infants to self-soothe and go back to sleep. Once babies no longer need nighttime feedings, usually around 4-5 months old, they can learn to fall asleep independently and stay asleep longer. The app aims to assist in developing good sleep associations and behaviors for babies to establish healthier sleep patterns.

The app features full documentation on the training method, an easy-to-use trainer that runs in the background, a training log for tracking progress and adding notes, an advanced sleep wait time editor for customization, optional social sharing of sleep success, and an Apple Watch app for convenient control of the sleep training process.
