Fortunately, most children these days are pictures of robust health — energetic, engaged, and well cared for. They have received their immunizations, are eating good food, and getting plenty of rest, love, and support. These are all things that help to create a strong, healthy person. Understanding how to keep your child healthy means knowing how to give him medicine, how to prevent accidents and help him recover from them, and how to deal with health issues, whether minor or serious.
