Diarrhea in a 10-Month-Old Baby

Updated July 19, 2017

Although many babies suffer from diarrhoea at one time or another, it can turn into a serious condition. With a 10-month-old, it is important to determine if he is in fact suffering from diarrhoea and to avoid dehydration. Always call your paediatrician if you have major health concerns or questions about your child's condition.


Depending on how much solid food your 10-month-old eats, a regular bowel movement can range from loose to well-formed, according to If your baby has a stool every now and then that is loose, that is likely normal. However, if his bowel movements change drastically and quickly, then he probably has diarrhoea.


Several different things can cause diarrhoea in a 10-month-old, from a virus or a bacterial infection to a parasite. Antibiotics can also cause diarrhoea, according to, so keep that in mind if your baby is taking antibiotics for an infection. Depending on how much solid food your baby eats, food allergies can cause diarrhoea. Keep track of everything your child eats, especially when introducing new foods. Also, keep track of how much juice your child drinks. Drinking too much fruit juice can also cause diarrhoea. According to, 10-month-olds should have no more than 118ml of juice per day.


Make sure to offer your baby plenty of fluids while he is having diarrhoea to avoid dehydration. Continue to give him formula or breast milk and solids as long as he tolerates it. Only use a paediatric electrolyte solution under the guidance of a doctor. Although many parents limit what their child eats while having diarrhoea to the BRAT diet--bananas, rice, applesauce and toast--according to, the AAP recommends maintaining your baby's normal diet as much as possible. Yoghurt with active cultures can also help alleviate diarrhoea.

What to Avoid says to avoid making your own electrolyte liquid if your baby cannot tolerate formula or breast milk--use store-bought electrolyte liquids made for children only. Do not give your baby anti-diarrhoea medication unless instructed by a doctor. Do not prevent your child from eating if she is hungry, but try to avoid salty broths and soups.

When to Call the Doctor recommends calling your paediatrician if your baby shows signs of dehydration, which includes crying without tears, dry mouth and not having a wet diaper for six hours. Also call the doctor if your child develops a fever of 38.9 degrees C or higher, or shows any major change in behaviour, states
