For parents
Why health learning matters.
Small daily habits, learned early, protect children for a lifetime.
Eating, sleep, activity and hygiene habits formed in childhood often last a lifetime.
Kids who sleep well, eat well and move every day focus, remember and behave better at school.
Naming feelings and asking for help builds resilience, and mental health is as important as physical health.
Knowing what to do in an emergency, from calling for help to Hands-Only CPR, can save a life.
