When Can My Baby Start Drinking from a Cup?
Content reviewed against published AAP, CDC, AAP guidelines
Last reviewed:
Feeding challenges are one of the most common concerns new parents face. When it comes to when can my baby start drinking from a cup, here is what the guidelines recommend.
The short answer
You can begin introducing an open cup or straw cup around 6 months of age when your baby starts solids. Initially, offer just small sips of water during meals for practice. Babies do not need to be proficient cup drinkers right away - it is a skill that develops gradually. Speech-language pathologists and feeding therapists generally recommend open cups or straw cups over traditional sippy cups, as they promote better oral motor development.

- Usually normal when: Your 6-9 month old mostly dribbles water when you offer a cup - they are just learning the mechanics.
- Call your doctor if: Your baby is choking or aspirating (liquid going into lungs) when drinking from any vessel, including bottles.
- Varies by age — see the age-by-age breakdown below
“The AAP recommends exclusive breastfeeding for approximately 6 months after birth. Furthermore, the AAP supports continued breastfeeding, along with appropriate complementary foods introduced at about 6 months, for 2 years or beyond.”

By Age
What to expect by age
6-9 months
Start by offering a small open cup (like a tiny shot glass or a specially designed baby open cup) with just a tablespoon or two of water during mealtimes. Guide the cup to your baby's lips and tilt slowly. Expect spilling - this is part of the learning process. You can also introduce a straw cup by teaching your baby to draw liquid up through the straw. Some parents use a technique of placing a straw in liquid, covering the top with their finger to trap the liquid, and releasing it into the baby's mouth to teach the concept.
9-12 months
By this age, many babies can hold and drink from an open cup with some assistance, though spills are still expected. Straw drinking may be more proficient. Offer water in a cup at all meals and snacks. You can begin offering breast milk or formula in a cup at one meal per day to begin the bottle-weaning process. This is a motor skill - some babies get it quickly while others need more practice. The key is regular, pressure-free exposure.
12-24 months
By 12-15 months, most toddlers can drink from a straw cup independently and are working on open cup skills with some spillage. The AAP recommends weaning from bottles by 12-18 months, so this is the time to make cups the primary drinking vessel. Offer cow's milk (or alternative) in a cup rather than a bottle. Most toddlers master open cup drinking with minimal spilling by 18-24 months. Regular sippy cups with spill-proof valves are not ideal for oral motor development, though they can be convenient for on-the-go use.
What Should You Do?
When to take action
- Your 6-9 month old mostly dribbles water when you offer a cup - they are just learning the mechanics.
- Your baby can drink from a straw cup but still spills from an open cup at 12 months.
- Your toddler prefers a straw cup over an open cup - both are developmentally appropriate.
- Your baby initially rejects the cup and only takes small sips - it takes time and repeated exposure.
- Your baby is over 12 months and refuses all cups, only accepting bottles.
- Your child consistently chokes or coughs when drinking from any cup past 12 months.
- Your toddler is over 18 months and cannot manage any form of cup drinking despite regular practice.
- Your baby is choking or aspirating (liquid going into lungs) when drinking from any vessel, including bottles.
- Your child is showing signs of dehydration because they refuse all cups and you are weaning from bottles.
- Your child has persistent difficulty swallowing liquids that seems to be getting worse rather than better.

Transitioning My Baby from Bottle to Cup
The AAP recommends beginning to introduce a cup around 6 months and weaning off bottles by 12-18 months. Prolonged bottle use is associated with tooth decay, iron deficiency, and excess calorie intake. The transition can be gradual - start by offering a cup at one meal, then slowly replace more bottle feeds. Open cups and straw cups are preferred over sippy cups as they promote better oral motor development.
Best First Finger Foods for Baby
Finger foods can be introduced when your baby can sit upright with minimal support, has good head control, and shows interest in food - typically around 6-9 months. The best first finger foods are soft enough to mash between your fingers, cut into safe shapes (long strips for younger babies, small pieces for babies with pincer grasp), and include a variety of nutrients. Good options include ripe banana, avocado, soft-cooked sweet potato, and steamed broccoli florets.
Signs of Fine Motor Delay in Babies and Toddlers
Fine motor skills - the small, precise movements of the hands and fingers - develop gradually throughout the first few years. Key milestones include reaching for objects (3-5 months), raking grasp (6-7 months), pincer grasp (8-10 months), and using a spoon or crayon (12-18 months). Mild variations in timing are normal, but significant delays across multiple fine motor skills may warrant an occupational therapy evaluation. Early intervention can make a significant difference.

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.
When Does My Baby Need Amino Acid Formula?
Amino acid-based formulas (also called elemental formulas) are prescribed for babies with severe cow's milk protein allergy, multiple food protein intolerances, or conditions like eosinophilic esophagitis who cannot tolerate standard or extensively hydrolyzed formulas. They are the most hypoallergenic formula available because the proteins are broken down into individual amino acids, making allergic reactions virtually impossible.
