Feeding challenges are one of the most common concerns new parents face. When it comes to sippy cup vs straw cup: which is better, here is what the guidelines recommend.
The short answer
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.
Key takeaways

- Usually normal when: Baby prefers one cup type over another
- Call your doctor if: Baby cannot drink from any vessel and is not getting adequate fluids
- 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.”
Thousands of parents search for this exact thing. You are not alone.
What Parents Should Know
According to AAP, NIH guidelines, 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. At 0-3 months, cups are not appropriate at this age. Breast or bottle feeding only. It is generally considered normal when baby prefers one cup type over another. However, you should contact your pediatrician promptly if baby cannot drink from any vessel and is not getting adequate fluids.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
Cups are not appropriate at this age. Breast or bottle feeding only.
4-6 months
Around 6 months, you can introduce an open cup (held by you) for small sips of water. This builds the best oral motor patterns from the start.
6-9 months
Offer a straw cup or open cup for practice. A weighted straw cup can be easier for baby to manage. If using a sippy cup, it is fine for transition but plan to move to a straw or open cup.
9-12 months
Baby should be getting comfortable with a cup type. Straw cups encourage a more mature swallowing pattern than sippy cups. Try a short straw or use the straw-dipping technique to teach straw drinking.
12-24 months
Aim to move past traditional sippy cups. Straw cups and open cups (with some spillage) are the best options. 360 cups are a popular choice but some speech therapists note they still require a sucking pattern. Open cups with handles are great for mealtimes.

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.
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.
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.
