Development
What your child is doing, in their own time
Milestones are a conversation, not a test. AVYOMI shows 159 source-attributed CDC observations across 12 checklist ages, selected automatically for your child's age.
Framework live
Four domains, never a single score
Movement & physical
Whole-body movement and hand skills are kept together exactly as the source framework defines them.
Language & communication
Responding to sound, babbling, first words, following instructions, joining words together.
Cognitive
Looking for hidden objects, cause and effect, simple problem-solving, pretend play.
Social & emotional
Smiling in response, stranger awareness, sharing attention, playing alongside others.
12 checklist ages
The staged framework covers 2, 4, 6, 9, 12, 15, 18, 24, 30, 36, 48 and 60 months.
Checksum locked
Every item is linked to its official CDC page and one immutable import checksum. The published framework cannot be silently changed.
Observation states
Achieved, emerging, or not yet
AVYOMI records nuanced observations with dates rather than forcing a diagnostic score.
Choose Yes, Not yet, Not sure, or Haven't watched for it — uncertainty is never forced into a score.
Between checklist ages the younger checklist is used; corrected age is used for babies born more than three weeks early.
A private note and first-observed date can travel with each response into your child's record.
The checklist supports developmental monitoring conversations and never replaces validated screening or diagnosis.
