Lunara's AI insights feature analyses your baby's sleep, feeding, growth, and milestone data together and delivers a personalised weekly digest every Sunday morning. Each insight includes a confidence score and a plain-language explanation with a specific recommended action never medical jargon. Learn more about how AI parenting insights work.
