For educational purposes only
This guide is educational information for parents and caregivers about children's health — it is not medical advice, diagnosis, or treatment, and it is not a substitute for care from a qualified pediatrician or doctor. It does not diagnose, treat, cure, or prevent any condition. See your child's doctor for check-ups, vaccinations, and any concern, and follow your pediatrician and your national immunization schedule. Trust your instincts: seek urgent care for a high fever in a young infant, trouble breathing, signs of dehydration, unusual drowsiness or unresponsiveness, or a rash that doesn't fade under pressure; in an emergency, call 911.
