Constipation, diarrhoea, flatulence and issues with bowel movement are just a few examples of concerns that mums have about a child's digestion. Here are five things you should know about your baby's digestion to help ease their discomfort and promote regular bowel movement.  

  1. Check for both consistency and frequency 

When trying to determine if your baby is suffering from constipation, check how many times they pass stool and note its color and consistency1. Your child's bowel movement is normal if their stool is soft and easy to pass.  

  1. Stretching is not a cause of diarrhoea 

Your child's growth or motor development won't cause issues with their bowel movement. If your child is experiencing issues, they may have an infection from being able to reach different things and putting these in their mouths, leading to the ingestion of germs.  

If you recently changed your child's diet, this may also cause diarrhoea. Make sure to note what food you introduced to your baby and how your child reacts to each.  

  1. Passing gas is normal 

There are several reasons your baby keeps burping or is passing gas2:  

  • They may have swallowed air while drinking and eating, which is either released through the anus as gas or manifests as hiccups.  

  • The food and drinks your baby tries have varying levels of gas, so they can be gassy depending on what new food they've tried.  

  • If your baby can't digest lactose easily, they may experience gas and bloating. 

As your child's digestive system develops and produces more gastric juice, the gas will eventually go away.  

  1. Turning red while defecating isn't a sign of pain 

Because your child doesn't know yet how to push gradually, their tendency is to push too hard, which causes them to turn red in the face. Help ease their bowel movement by massaging their stomach clockwise.  

Check instead if your baby has marble-looking stool—this is a sign of constipation and may be causing your child discomfort. If you notice blood in the stool and your baby has not had bowel movement in days, consult your paediatrician3.  

  1. Dietary changes helps facilitate digestion 

Your baby becomes more accustomed to solid food after a year old. As a result, their bowel movement changes as well, resulting in either diarrhoea or constipation. Make sure to introduce one type of food over a span of 3-5 days to identify any adverse reactions to the food that your child may have4. Additionally, introducing fruits and vegetables to their diet will help facilitate bowel movement and help prevent constipation5. Most importantly, keep your baby hydrated.
