Children with weakened immune systems or pre-existing conditions will need to see a doctor for even minor illnesses and injuries. If your child is healthy, does not have a disease or illness, it is okay to see if your child will get better on their own.
There are some symptoms that should be a red flag that you should seek pediatric care now. If you child is having trouble breathing, has a high fever that is not responding to treatment, acts lethargic, or you suspect dehydration you should seek immediate medical assistance.
If you child has a low grade fever it is okay to wait a day and see if they show any improvements. As a parent, you can usually tell when your child is really sick, or when they have a common cold. If you are concerned, or are not sure what to do, consult a pediatric doctor for advice.
