When Should Babies Start Drinking Water After Starting Solids?

Why Isn’t Water Recommended Before 6 Months?

According to the World Health Organization (WHO) and pediatric associations:

  • Exclusive breastfeeding or formula is sufficient for hydration in the first 6 months
  • Breast milk is 88% water, meeting all fluid needs—even in hot weather
  • Giving water too early can fill a baby’s small stomach, reducing milk intake
  • It may disrupt electrolyte balance, rarely leading to water intoxication

Introducing water too soon may interfere with nutrition, weight gain, and immune benefits of breast milk.

When Can Babies Start Drinking Water?

  • Water can be introduced at 6 months, when babies begin eating solid foods
  • It helps babies get used to the taste and habit of drinking water
  • Start with just 1–2 teaspoons (5–10 ml) per meal

Water should never replace breast milk or formula. It’s a supplement—not a substitute.

Water Needs for Babies 6–12 Months Old

Age

Daily Water Intake

Notes

6–9 months

30–60 ml (2–4 tbsp)

Start small and increase gradually

9–12 months

100–150 ml

May increase in warm weather
  • Most fluid needs are still met through breast milk or formula
  • No need to force water—offer it after meals or between feedings

Guidelines for Introducing Water

1. Use Clean and Safe Water

  • Boiled and cooled tap water is ideal
  • Avoid giving untreated tap water or high-mineral bottled water
  • For bottled water, check for baby-safe mineral levels

2. Offer in an Open Cup or Training Cup

  • Skip the bottle—use a small open cup or sippy cup
  • Encourages oral motor development and reduces bottle dependency

3. Avoid Offering Water Before Meals

  • Can reduce appetite for solids or milk
  • Best time: after meals or between feedings

Does Water Need Increase in Summer?

Yes—babies may sweat more or lose fluids during:

  • Hot weather
  • Mild illness
  • Increased physical activity (crawling, playing)

Water intake can be gently increased under medical guidance, but breast milk or formula remains the primary fluid source under 1 year.
