FAQ

What is the M-CHAT?

A short parent questionnaire used as a screening tool. It flags kids for a closer look — it doesn’t diagnose anything.

My toddler has fewer than 10 words — should I worry?

Bring it up; a speech evaluation through Early Intervention is free and low-friction in most states.

Is screen time a big deal?

Current guidance generally recommends limiting screen time for toddlers. Your pediatrician can talk through what’s practical.
