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 baby, call your health care provider right away. Well-baby visits are important to your baby's health. A newborn usually needs to be seen by a health care provider every few months. As children reach their first birthday, most do not need to go as often. Babies will get their recommended immunizations 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 .
