Feeding challenges are one of the most common concerns new parents face. When it comes to spills everything with an open cup, here is what the guidelines recommend.
The short answer
Spilling is a completely normal and expected part of learning to drink from an open cup. This is an important developmental skill that takes months to master. Start with very small amounts of liquid and expect a lot of mess. Most babies become reasonably proficient with an open cup between 12 and 24 months.
Key takeaways
- Spilling is a completely normal and expected part of learning to drink from an open cup. This is an important developmental skill that takes months to master. Start with very small amounts of liquid and expect a lot of mess. Most babies become reasonably proficient with an open cup between 12 and 24 months.
- Usually normal when: Baby spills frequently while learning to use an open cup
- Call your doctor if: Baby appears unable to coordinate swallowing liquids from any vessel
- 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.”
This is one of the most common questions parents ask. Searching for answers means you care.
What Parents Should Know
According to AAP, CDC guidelines, spilling is a completely normal and expected part of learning to drink from an open cup. This is an important developmental skill that takes months to master. Start with very small amounts of liquid and expect a lot of mess. Most babies become reasonably proficient with an open cup between 12 and 24 months. At 0-3 months, open cup practice is not appropriate for babies this young. Focus on breast or bottle feeding. It is generally considered normal when baby spills frequently while learning to use an open cup. However, you should contact your pediatrician promptly if baby appears unable to coordinate swallowing liquids from any vessel.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
Open cup practice is not appropriate for babies this young. Focus on breast or bottle feeding.
4-6 months
Around 6 months, you can begin offering tiny sips from a small open cup that you hold. Expect most of the liquid to dribble out. This early exposure helps baby learn the concept even though they will not be proficient for many months.
6-9 months
Continue offering sips from an open cup that you hold. Baby is learning jaw stability and lip closure on the cup rim. Use a very small cup with only a tablespoon or two of liquid to minimize mess. Spilling is a necessary part of the learning process.
9-12 months
Some babies start trying to hold the cup themselves, which means more spilling. This is great practice for coordination. Use a small cup that is easy for baby to grip. Continue offering only small amounts at a time. Some babies do better with a slightly weighted cup that tips more slowly.
12-24 months
Toddlers are developing the coordination to drink from an open cup with less spilling, but expect messes to continue. By 24 months, most toddlers can drink from an open cup with reasonable success. If your toddler still cannot bring an open cup to their mouth by 18 months, mention it at your next well visit.
What to Tell Your Pediatrician
- Describe when you first noticed spills everything with an open cup and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if baby is over 18 months and cannot bring a cup to their mouth.
- Mention if baby has difficulty with lip closure on the cup rim.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Baby spills frequently while learning to use an open cup
- Baby tilts the cup too far and pours liquid on themselves
- Baby prefers to play with the water in the cup rather than drink it
- Baby can take a few sips but then dumps the rest
- Baby is over 18 months and cannot bring a cup to their mouth
- Baby has difficulty with lip closure on the cup rim
- Baby consistently coughs or chokes when drinking from an open cup
- Baby appears unable to coordinate swallowing liquids from any vessel
- Baby aspirates or inhales liquid every time they try to drink
What You Can Do at Home
- Keep track of when you notice spills everything with an open cup — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that baby spills frequently while learning to use an open cup — this is generally within the range of normal.
- At 0-3 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Offer feeding in a calm, distraction-free environment. Avoid forcing or pressuring your baby to eat.
- While monitoring at home, seek immediate care if baby appears unable to coordinate swallowing liquids from any vessel.
Related Conditions
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.
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.
Sippy Cup vs Straw Cup: Which Is Better?
Speech therapists and pediatric dentists generally recommend straw cups and open cups over traditional spout sippy cups. Sippy cups require a sucking motion similar to a bottle, while straw cups develop more mature oral motor patterns important for speech. Open cups help develop lip and jaw control. If you use a sippy cup, consider it a transitional tool rather than a long-term solution.

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.
