Can an 8-Month-Old Drink Water?
Yes, an 8-month-old infant can and should be offered small amounts of plain water with meals, while breast milk or formula remains the primary fluid source. 1, 2
Primary Fluid Requirements
At 8 months of age, your infant's hydration needs are still primarily met through breast milk or infant formula, which must continue as the main fluid source throughout the first year of life. 1, 2 These provide complete hydration and essential nutrients that water cannot replace. 1
How to Offer Water Safely
- Offer water in small amounts (a few ounces) alongside meals when solid foods are being consumed. 1, 2
- Use a cup rather than a bottle to promote proper feeding development and reduce dental risks. 1, 2
- Tap water is acceptable and provides beneficial fluoride for dental health. 1, 2
Critical Safety Warnings
Excessive water intake can cause hyponatremia (dangerously low blood sodium), which can lead to seizures and other serious complications in infants. 1, 2 This is why water should only be offered in modest amounts—too much water displaces nutrient-dense breast milk or formula, potentially leading to malnutrition. 1
What to Avoid
- Never give fruit juice to your 8-month-old, as the American Academy of Pediatrics explicitly states juice should not be introduced before 12 months of age unless clinically indicated. 3, 1, 2
- Do not use water in bottles at bedtime, as this can contribute to dental caries. 1, 2
- Do not allow your infant to carry around bottles or cups of water throughout the day, as this displaces essential nutritional intake from breast milk or formula. 1, 2
Feeding Pattern at 8 Months
Continue breastfeeding on demand or offering formula as the primary nutrition source. 2 Solid foods should be offered every 3-4 hours, with water provided in small amounts during these meals. 2
