Water Intake Guidelines for Infants Starting Solid Foods

Introduction to Water Intake

• The American Academy of Pediatrics recommends offering small amounts of plain water with meals to 6-month-old infants starting solid foods, while prioritizing breast milk or formula as the primary fluid source 1

Primary Fluid Source

• Breast milk or infant formula continues to provide complete hydration even after 6 months of age and must remain the primary fluid source throughout the first year of life 1

Appropriate Water Introduction

• Offer water in small amounts (a few ounces) alongside meals once solid foods are introduced at approximately 6 months of age 1
• Water should be offered in a cup rather than a bottle to promote proper feeding development and reduce dental risks 1

Critical Safety Considerations

• Excessive plain water can cause hyponatremia (low blood sodium), which can lead to seizures and other serious complications in infants 1
• Tap water is acceptable and contributes beneficial fluoride intake for dental health 1

Feeding Patterns

• Freshly prepared foods including cereal and beans or cereal and meat with vegetable oil should be offered every 3-4 hours to 6-month-old infants 2
• Breastfed infants should continue nursing on demand without interruption 2

What to Avoid

• Never give fruit juice to infants under 12 months of age unless specifically indicated for a medical condition like constipation 1
• Do not use water or any liquid other than breast milk/formula in bottles at bedtime to prevent dental caries 1
• Do not allow infants to carry around bottles or cups of water throughout the day, as this displaces nutritional intake 1
