Open the right age
Start with the current developmental-age checklist or browse earlier and future age bands.
From 2 months through 5 years
Lullalog turns the CDC’s age-based developmental milestone checklists into illustrated rows you can understand, record and revisit with the rest of your child’s care history.
Informational—not developmental screening or diagnosis.

A checklist designed for observation
Milestones are easier to use when the app separates learning about a skill from deciding that you observed it.
Start with the current developmental-age checklist or browse earlier and future age bands.
Tap an illustrated milestone row for an explanation and a natural way to watch for it.
Tick the circle and keep the reached date. You can adjust the date if you noticed it earlier.
Clear detail without false certainty
Lullalog’s detail cards add practical context and illustrations while keeping the checklist’s role narrow.
The content is based on the CDC’s developmental milestones, which describe things most children—75% or more—can do by each age. It is not a screening or diagnostic tool. Talk with your child’s clinician if you have concerns or your child has lost skills.
