Toys are sorted by shipping box, not by what's changing in vision, grip and memory right now — so bins fill with things already outgrown or too advanced.
No quiz, no score — just the week we plan around.
3–5 pieces built for this exact window, not a crate.
Two or three specific prompts to use during play.
Bold patterns sized for newborn vision, 0–3 months.
Respond instantly to a kick, swat or grasp.
Peekaboo boxes sized for searching-age babies.
Words and pauses to use with baby, every stage.
Each stage maps to one published study, not marketing copy.

No — it doesn't exist as a physical product yet. Once built, pieces will be tested to standards like ASTM F963 before sale.
No. Windows are typical ranges from published research, not promises. Every baby paces themselves; no toy guarantees an outcome.
You'll be able to move a stage earlier or later — windows are ranges, not deadlines.
