LullaStage
A weekly music-coaching app for parents of 0–12 month olds that picks age-appropriate music and tells you exactly what listening and movement responses to look for, grounded in current developmental research.
First-time parents of infants 0–12 months who want more than a generic lullaby playlist
- Age-adaptive weekly curation in three tiers (3m, 6m, 12m) with research-backed track picks
- 'What to expect today' video clips showing typical responses (rocking, swaying, clapping by 12m)
- Optional camera-based movement capture so parents can compare their baby's spontaneous response to the norm
- High-pitch tip: brief notes on why higher-pitched tracks predict movement at every age, with curated tracks
