How can we help?

LULU tracks your baby's sleep and feeding patterns and tells you when it's a good time for the next nap. It's designed specifically for families of preemies, multiples, and low birthweight babies using corrected age. It is not a medical device — all information is for reference only.

Corrected age (also called adjusted age) is used to assess premature babies' development. Instead of counting from the birth date, it counts from the original due date. LULU automatically calculates corrected age from the due date you enter and applies it to all sleep and feeding guidance.

Yes — LULU was built with multiples in mind. Each baby gets their own separate tab with independent corrected age, sleep, and feeding tracking. There are no comparisons between babies by design.

LULU gets more accurate as it builds a picture of your baby's individual pattern. In the early days it starts from general guidelines, then adjusts with each log. During sleep regressions (around 4 months, 8 months, etc.) patterns can shift temporarily — always follow your baby's cues over the app.

Tap the quick-log button at the bottom of the home screen. You can log breast, formula, and mixed feedings. Once you have enough logs, LULU will start predicting the next feeding time.
