We watched one mom hand her baby over 50 toys in a single hour. Across 100+ interviews, it was the same story — parents bored and exhausted, trying to fill the hours with things designed for minutes.
The user is the adult. Adventures are themed around things grown-ups actually want to do — the beach, a planetarium, a magic show.
Games and stories that get the caregiver interacting with their baby, which research shows is the best thing for their brain development. (A baby's brain develops 25% in the first year.)
No screens needed — the narration guides every moment of playtime, and adventures use common household objects only. No prep. Just press play.
US toy sales grew just 3% from 2020 to 2025, barely tracking inflation. And 2025's growth came almost entirely from adult collectibles, not baby toys.
"Analog living" is shaping up to be one of the biggest parenting trends of 2026. Haidt's Anxious Generation sparked a movement of "screen-free parenting." 62% of parents now feel guilty about screen time.
Yoto: +86% YoY to $128M (2024). Tonies: +31% YoY to €630M (2025). Together they've built a billion-dollar category in five years — entirely screen-free.
