When your baby is sick for the first time, it can be one of the scariest things that happens to you as a new parent. You will start wondering when to call the doctor for your baby. Should you call the pediatrician at the first sign of a runny nose, or wait until their child has not slept in days? The first thing all new parents need to realize is that babies get sick, just like children of any age. A sick baby does not mean you are a bad parent. In fact, getting a small cold once in a while helps your baby’s developing immune system become stronger. But any cold or sickness can develop into a difficult situation if not kept under control.
