About Toddler Health
Most young children get sick. It is hard for parents to know what is serious. You can learn what the common warning signs are. In the end, trust your intuition. If you are worried about your toddler, call your health care provider right away.
Well-child visits are important to your toddler's health. Toddlers will get their recommended vaccines during these visits. Routine exams and screenings help you and your kids prevent and treat health problems as well as chart their growth and development.
It sits within Children and Teenagers.
The lead U.S. institute for this subject is the Eunice Kennedy Shriver National Institute of Child Health and Human Development.
When to speak to someone. Reading about a topic cannot tell you whether it applies to you. Speak to a doctor or pharmacist if symptoms are severe, sudden, getting worse, or simply not going away — and seek emergency care immediately for chest pain, breathing difficulty, sudden weakness or confusion, or a serious allergic reaction.
Research on Toddler Health
25 studies areregistered for this condition on ClinicalTrials.gov, the U.S. National Library of Medicine's public registry. A selection is below — the links go straight to the registry entry, not to a summary of ours.
What a registered study does and does not mean. Registration means a study exists and has been declared publicly. It says nothing about whether the treatment being tested works, is safe, or is available to you. Many studies find no benefit — that is what research is for. Never seek out an experimental treatment on the strength of a registry entry alone.
