<bot>: The most important thing you can do to keep your children healthy is to make sure they are up-to-date on their vaccinations. Vaccines help protect children from serious diseases, such as measles and whooping cough. It's also important for parents to monitor their child's health closely and take them to the doctor if they show any signs of illness or fever.
