We write when we have something worth saying. About infant development, material science, the thinking behind our toys, and the questions we're still working to answer.
At birth, a human infant has approximately 20/400 vision. They see contrast, not colour. Movement, not detail. The toys that reach them in this window are not about stimulation — they're about introducing the idea of the object-world. Most toy design ignores this entirely.
Read the article →Biodegradable is not compostable. Industrial compostable is not home compostable. These distinctions are not marketing — they're chemistry. Here's exactly what LYKKEH uses and why.
The BIS IS 9873 standard is mandatory — but few parents know what it covers. We read the standard so you don't have to. Mechanical properties, migration limits, flammability: here's the breakdown.
At 6 months, an infant can exert approximately 0.7–1.2 kgf of grip force with one hand. This number shaped every dimension of the LYKKEH Ring Stacker. Design is not intuition. It's applied science.
Surface-applied lead paint on toys was globally phased out decades ago. In the Indian market, enforcement remains inconsistent. Here's what to look for and what test to ask for.
At 18 months, a child crosses from symbolic to representational play. The shift from stacking to building is a cognitive marker, not a toy recommendation. What this means for the toys you choose.
Silicone has dominated the premium infant toy market for a decade. But natural rubber has better flex, lower toxin potential, and a genuine biodegradation pathway. The trade-offs, honestly stated.
AZO dyes release carcinogenic aromatic amines under reducing conditions — like the acidic environment of an infant's gut. The EU banned 22 specific amines decades ago. The Indian standard permits them under limits. LYKKEH uses none.
Primary red has dominated infant toy design since Mattel. The colour exists because it sells on shelves, not because it's developmentally correct. We chose differently. The research behind the decision.
The small-parts cylinder is 4.5cm diameter × 6.0cm depth. Any part that fits entirely inside it is a choking hazard. This is not a guideline — it is a hard design rule. LYKKEH's minimum part dimension is 48mm.
