When There’s Blood in Your Baby’s Stool and You Start to Worry
Your baby may be feeding well and gaining weight, yet you notice streaks of blood or mucus in their stool. Even when your baby appears comfortable, the sight can be frightening and raise many questions. At Joyful Seeds Paediatric & Development Clinic in Bukit Timah, we help parents make sense of these changes with clear, thoughtful support and evidence-based care.
Allergic colitis is a common cause of blood-streaked stools in young babies. It is usually not dangerous and can be well managed with the right guidance. Our aim is to help your baby feel well and support your confidence as a parent through each step of this journey.
What Is Allergic Colitis
Allergic colitis is a type of food protein-induced condition that affects the large intestine. It often appears in healthy infants during the first few months of life. It is triggered by proteins in milk, either from formula or passed through breast milk from the mother’s diet.
This condition is not the same as a true food allergy. It does not involve life-threatening reactions or affect other organs. Instead, it causes irritation in the intestines that leads to blood or mucus in the stools.
With appropriate feeding adjustments, most babies outgrow allergic colitis by their first birthday.
What You Might Notice
Many babies with allergic colitis appear happy and well apart from their stool changes. However, there are some key signs to watch for.
Blood or Mucus in Stool
You may notice small streaks of blood, pinkish spots or mucus in your baby’s nappy. These can appear daily or intermittently and are often noticed during routine changes.
Mild Digestive Changes
Some babies may pass more frequent stools or have episodes of mild diarrhoea. Others may show slight discomfort while passing motion, though many remain content.
Feeding and Growth Are Usually Normal
Most babies continue to feed well and grow steadily. There may not be any vomiting, severe fussiness or weight loss, which helps distinguish this condition from more serious digestive concerns.
