About Sprout's content
Sprout summarizes general developmental science for the newborn months. It is educational and cannot tell you how your particular baby is doing. Milestones are shown as typical ranges, not deadlines — healthy babies vary enormously in their timing. If anything ever worries you, your pediatrician is the right person to ask.
Grounded in
- American Academy of Pediatrics — Your Baby's First Year & HealthyChildren.org
- Mayo Clinic — Infant development (birth–6 months)
- American Academy of Ophthalmology & AOA — infant vision development
- Peer-reviewed neuroimaging on cortical myelination & synaptogenesis (PMC / bioRxiv)
- Sleep Foundation & AAP — newborn sleep and circadian rhythm
- ZERO TO THREE — early brain development
Not medical advice. Sprout does not diagnose or replace care from your pediatrician. Content is richest for the first ~3 months.
