When Is My Baby Ready for an Open Cup?
The short answer
Most babies can begin practicing with a small open cup around six months of age, when they start solids. Early attempts will be messy, and that is completely expected. Open cups are recommended over sippy cups by most feeding therapists because they promote better oral motor development and are easier to transition to long term.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
Before six months, babies get all their liquid from breastmilk or formula and do not need supplemental water or cup practice. Around six months, as you introduce solids, you can begin offering a few sips of water from a small open cup held by a caregiver. Expect most of the water to dribble out, and keep the amounts tiny.
This is the ideal window to introduce an open cup. Start by holding a small cup to your baby's lips and tipping it gently. Over time, your baby will begin to reach for and hold the cup independently. Many babies can take several sips from an assisted open cup by nine months. Straw cups are also a good option during this stage, as they promote a more mature swallowing pattern than sippy cups.
By 12 to 15 months, many toddlers can independently drink from a small open cup with some spilling. By 18 to 24 months, most toddlers can drink from an open cup with minimal spills. If your toddler is still exclusively using bottles or sippy cups, now is a good time to actively practice open cup skills at meals. The AAP recommends weaning from bottles by 12 to 15 months.
Most toddlers should be proficient with an open cup by this age. If your child still strongly resists or cannot manage an open cup, it may be worth mentioning to your pediatrician, as difficulty drinking from a cup can sometimes indicate oral motor challenges that benefit from evaluation.
What Should You Do?
When to take action
- Your baby spills frequently when first learning to use an open cup, especially before 12 months
- Your baby takes only tiny sips at a time and loses interest quickly
- Your baby alternates between wanting the cup and pushing it away during the learning phase
- Your toddler has some spills even after months of practice, since full cup proficiency often takes until age two or beyond
- Your baby coughs or chokes frequently when taking sips from any cup after multiple weeks of practice
- Your toddler over 18 months shows no interest in or ability to use any type of cup
- Your child seems to have difficulty controlling liquids in their mouth and frequently loses liquid out the sides
- Your toddler exclusively drinks from a bottle past 15 months despite consistent cup practice
- Your baby chokes severely on liquids and turns blue or cannot breathe
- Your baby seems unable to swallow liquids and liquid consistently comes out of the nose

Related Feeding Concerns
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.
Baby Biting Nipple While Nursing
Biting during breastfeeding is a common challenge, especially when babies start teething. It can be startling and painful, but it is almost always a phase that can be managed. Babies cannot actively nurse and bite at the same time because their tongue covers the lower teeth during proper sucking. Biting typically happens at the beginning or end of a feed when the latch is not active. With some gentle strategies, most babies learn quickly that biting ends the feeding session.
My Baby Keeps Clamping Down on the Spoon
Clamping down on the spoon is very common, especially during teething or when babies are learning new oral motor skills. It is often a sensory exploration behavior rather than a feeding problem. Using a soft silicone spoon and placing food on the front of the spoon can help.
How Can My Baby Get Enough Calcium Without Dairy?
If your baby cannot have dairy due to allergy or intolerance, there are many other calcium sources. These include calcium-fortified foods, broccoli, kale, tofu made with calcium sulfate, beans, calcium-fortified plant milks (after 12 months), and sardines. Breast milk and formula provide adequate calcium before 12 months. If dairy-free after 12 months, planning is important.
