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.

Posibles Causas

  • 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)

Qué Puedes Hacer

  • 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

¿Cuándo Consultar al Médico?

  • 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

Notas Según la Edad

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.

Preguntas Frecuentes

How do I recognise dehydration in my baby?
Key signs: fewer than 4 wet nappies in 24 hours, dry lips and mouth, sunken fontanelle (soft spot on head), crying without tears, loose skin (skin fold returns slowly). See a doctor immediately with these signs.
Should I stop breastfeeding during diarrhoea?
NO! Definitely continue breastfeeding. Breast milk contains antibodies and fluids your baby especially needs now. Breastfeeding is the best treatment for diarrhoea. Offer the breast more often.
Is green stool diarrhoea?
Green stool alone is usually not diarrhoea. It can be caused by solids (spinach, peas), foremilk when breastfeeding, or iron supplements. Diarrhoea is recognised by watery consistency and increased frequency, not by colour.
