Baby Diarrhoea
Diarrhoea in babies can quickly lead to dehydration. Breastfed babies naturally have softer stools — that is not diarrhoea. True diarrhoea is noticeably more watery, more frequent, and different-smelling than usual.
Possible Causes
- 1Viral gastroenteritis (rotavirus, norovirus) — most common cause
- 2Food intolerances (cow's milk protein, lactose)
- 3Teething (slightly softer stools possible, but not severe diarrhoea)
- 4Antibiotic side effect
- 5Introduction of solids (new foods can irritate the gut)
What You Can Do
- MOST IMPORTANT: fluid intake! Breastfeed more often or offer bottle
- Oral rehydration solution (ORS) from pharmacy for severe diarrhoea
- Continue breastfeeding — breast milk contains helpful antibodies
- For babies on solids: bland foods (banana, rice, grated apple)
- Clean nappy area frequently and protect with zinc cream
When to See a Doctor
- Signs of dehydration: dry lips, sunken fontanelle, fewer than 4 wet nappies in 24 hours
- Blood or mucus in stool
- Baby under 3 months with diarrhoea → see doctor immediately
- Diarrhoea with high fever (>39°C) or vomiting
- Baby seems lethargic, cries without tears, has dry skin
- Diarrhoea lasting more than 5-7 days
Age-Specific Notes
Newborns: Breastfed babies often have soft, mustard-yellow stools — this is NORMAL. 5-10 bowel movements per day can occur in exclusively breastfed babies. Infants: Stools change after starting solids — this is normal. Toddlers: Viral diarrhoea is common, watch for dehydration.
