Babies should not have water before 6 months of age because they get all the hydration they need from breast milk or formula. Giving water to babies under 6 months can lead to diarrhea, malnutrition, or electrolyte imbalances, and may cause them to drink less breast milk or formula, which provide essential nutrients and hydration. After about 6 months, when babies start eating solid foods, it is safe to introduce small amounts of water. At this stage, water helps them get used to its taste and learn to drink from a cup, but it should not replace breast milk or formula, which continue to be their main sources of nutrition and hydration until about 12 months. Between 6 and 12 months, babies generally need about 4 to 8 ounces of water per day, in addition to breast milk or formula. Water can be offered in a sippy cup in small amounts during meals. It is important to ensure water is safe—if tap water quality is uncertain, boiled and cooled water or bottled water can be used. In summary:
- No water for babies under 6 months.
- Introduce small amounts of water from 6 months with solid foods.
- Continue breast milk or formula as primary nutrition until 12 months.
- Offer about 4 to 8 ounces of water per day between 6 and 12 months.
- Use safe, clean water (boiled if necessary for under 12 months).
This guidance helps ensure proper hydration and nutrition while preventing risks associated with early water introduction.
