My Baby Won't Drink from a Cup
The short answer
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.

By Age
What to expect by age
Babies this age get all their fluids from breast milk or formula via breast or bottle. Cup drinking is not expected at this stage.
Around 6 months, you can start offering small sips of water in an open cup held by you. Baby will likely let most of the water dribble out, and that is completely normal. This is the very beginning of a long learning process.
This is a great time to practice cup drinking with small amounts of water during meals. Offer both open cups and straw cups to see which your baby prefers. Do not worry if baby plays with the cup more than drinks from it. Consistent exposure helps build the skill.
By 12 months, babies should be moving toward cup use. If your baby refuses all cups, try letting them play with an empty cup first, model drinking yourself, and try different cup types. Some babies prefer straw cups while others do better with open cups or 360 cups.
The AAP recommends weaning from bottles by 12-15 months. If your toddler still refuses all cups, try offering their favorite drink in a cup and nothing in a bottle. It may take a few days of adjustment. If your toddler cannot drink from any cup by 18 months, discuss it with your pediatrician.

Baby Refusing Sippy Cup
Many babies are initially uninterested in or resistant to sippy cups, and that is completely normal. The key is finding the right type of cup for your baby and offering it consistently without pressure. Some babies skip traditional sippy cups entirely and do better with straw cups or open cups with handles. There is no single cup that works for every baby, so trying a few different styles is often the solution.
My Baby Can't Figure Out How to Use a Straw Cup
Learning to drink from a straw is a new skill that takes practice. Most babies can learn between 6 and 12 months. You can teach by placing a straw in liquid, covering the top to trap liquid, and releasing it into baby's mouth. Some babies learn quickly while others need weeks of practice.
When Should My Baby Switch from Bottle to Cup?
The AAP recommends beginning to introduce cups around 6 months and weaning from bottles by 12-15 months. Prolonged bottle use can lead to tooth decay, excess calorie intake, and delayed oral motor development. Start by replacing one bottle with a cup and gradually replace the rest. The bedtime bottle is typically the last to go.
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.
