My Toddler Won't Drink Anything
The short answer
A toddler who refuses all drinks needs attention as dehydration can develop. If this is a sudden change, illness may be the cause. Try offering fluids in different cups, at different temperatures, and flavored with frozen fruit. Water-rich foods like watermelon, cucumber, and soup also contribute to hydration. If your toddler has not had adequate fluids for 12-24 hours, call your pediatrician.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
Babies this age who refuse breast milk or formula need immediate medical attention. Do not wait.
If a baby this age refuses breast milk or formula, contact your pediatrician promptly. Small amounts of water refusal are not concerning since breast milk or formula provides hydration.
If baby refuses water from a cup but still drinks breast milk or formula normally, this is not a concern. If they refuse all liquids including milk, seek medical advice.
If baby is refusing all liquids, check for illness such as sore throat or mouth sores (hand-foot-and-mouth disease). Offer cold liquids which may be soothing. Popsicles made from breast milk or purees can help with hydration.
Drink refusal in toddlers is often temporary and may be related to throat pain, mouth sores, or simple preference. Try different cups, straws, temperatures, and adding frozen fruit to water. Offer water-rich foods. If refusal persists more than 24 hours, watch for dehydration signs and contact your pediatrician.

Related Feeding Concerns
Baby Not Drinking Enough Water
Babies under 6 months do not need water at all because breast milk and formula provide all the hydration they need. In fact, giving water to young infants can be dangerous as it can cause electrolyte imbalances. After 6 months, small sips of water (2-4 ounces per day) can be introduced with meals as solids are started. By 12 months, toddlers should drink about 1-4 cups of water daily alongside their milk intake.
Baby or Toddler Refusing to Drink Water
Babies under 6 months should not have water at all - breast milk or formula provides all the hydration they need. After 6 months, small sips of water with meals can be introduced, but milk remains the primary fluid. Many toddlers prefer milk or juice over plain water, which is normal. Offering water in fun cups, adding fruit slices for flavor, and modeling water drinking yourself can help. Most toddlers get adequate hydration from milk and water-rich foods even if they do not drink much plain water.
My Baby Won't Drink from a Cup
Cup refusal is common, especially if baby is used to bottles or breastfeeding. Most babies can start learning to drink from an open cup or straw cup around 6 months. Patience and repeated exposure are key. Try different cup types, and remember that it is a skill that takes practice.
When to Introduce Allergens to Baby
Current guidelines recommend introducing common allergens (peanut, egg, cow's milk products, tree nuts, wheat, soy, fish, shellfish, sesame) starting around 4-6 months when your baby is developmentally ready for solids. The landmark LEAP study showed that early introduction of peanuts (by 4-6 months) reduced peanut allergy risk by 80% in high-risk infants. Do not delay allergens - the old advice to wait until 1-3 years has been reversed because early exposure actually prevents allergies.
I'm Worried My Baby Is Aspirating During Feeds
Aspiration means liquid or food enters the airway instead of the stomach. Occasional coughing during feeds is common and does not usually indicate aspiration. True aspiration is less common and may present as recurrent respiratory infections, a wet or gurgly voice after feeds, or chronic cough. If you are concerned, a swallow study can provide a definitive answer.
Could My Baby Be Aspirating During Feeding?
Aspiration occurs when food or liquid enters the airway instead of the esophagus. Signs include coughing or choking during every feed, a wet or gurgly voice after eating, recurrent chest infections, and breathing changes during meals. Silent aspiration can occur without obvious coughing. If you suspect aspiration, contact your pediatrician as a swallowing study can diagnose it.
