Children randomly assigned to a high-quality early care program from birth to age five showed significantly better health outcomes in their mid-thirties with the most striking effects on weight and cardiovascular health traceable to the first two years of life.

How this informs Toytilla Research: This finding informs the decision to recruit parents of newborns at the hospital at the point of birth. This is the same critical window identified by the ABC program. This will allow us to recruit a cohort at a similar age and at a critical juncture to examine whether structured developmental milestone education influences purchasing behavior and child outcomes before institutional intervention is even possible.

Even among college-educated parents with access to health resources, significant gaps in knowledge of typical developmental milestone trajectories persist.

How this informs Toytilla Research: If educated, resource-rich parents lack milestone knowledge, the gap is likely wider in broader populations. This study tests whether a simple, structured milestone review at the point of purchase can meaningfully close that gap.

The age at which children reach developmental milestones correlates with adult outcomes including IQ, educational attainment, and physical activity across multiple countries.

How this informs Toytilla Research: Pediatricians have seen the research that milestones predict long-term outcomes. This justifies using the CDC milestone checklist as the primary outcome measure in our follow-up assessment and using the checklist with the test group.

A secure bond with a caregiver gives children the confidence to explore the world while knowing they have a safe place to turn when they need comfort, and this sets them up for healthier relationships and emotional wellbeing down the line.

How this informs Toytilla Research: While much existing research focuses on training professionals to support child development, shifting consumer markets toward helping parents select developmentally appropriate toys may offer a more scalable and cost-effective path.

The CDC Learn the Signs. Act Early. program provides freely available, evidence-informed milestone checklists designed to support parent-provider conversations.

How this informs Toytilla Research: The CDC checklist serves as our primary outcome measure because it is validated, freely available, and designed for parent report, which makes it feasible for use across both phases of the study.
