Patient information: Diarrhea in children (The Basics)
Written by the doctors and editors at UpToDate
How often should my child have a bowel movement?
— It depends on how old he or she is:
●In the first week of life, most babies have 4 or more bowel movements each day. They are soft or liquid. It is normal for some babies to have 10 bowel movements in a day.
●In the first 3 months, some babies have 2 or more bowel movements each day.
●By age 2, most children have at least 1 bowel movement each day. They are soft but solid.
●Every child is different. Some have bowel movements after each meal. Others have bowel movements every other day.
How do I know if my child has diarrhea?
— It depends on what’s normal for your child:
●For babies, diarrhea means that bowel movements are happening more often than normal. Your baby might have twice as many bowel movements as he or she usually has. (In babies, normal bowel movements can be yellow, green, or brown. They can also have things that look like seeds in them.)
●Older children with diarrhea will have 3 or more runny bowel movements in a day.
What are the most common causes of diarrhea in children?
— The most common causes are:
●Side effects from antibiotics
What should my child eat and drink when he or she has diarrhea?
— Your child can continue to eat a normal diet. OK foods include:
●Rice, potatoes, and bread
●Fruits and vegetables
●Milk (unless the child has problems digesting milk)
What foods and drinks should my child avoid?
— These foods might make diarrhea worse:
●Foods that are high in fat
●Drinks with lots of sugar
What can I do to treat my child’s diarrhea?
