My Baby Can't Figure Out How to Use a Straw Cup
The short answer
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.
Thousands of parents search for this exact thing. You are not alone.
By Age
What to expect by age
Straw cups are not appropriate for babies this age. All nutrition should come from breast milk or formula.
Some babies can start learning straw drinking around 6 months, but many are not ready yet. If you want to introduce a straw, try the straw dipping technique: dip a straw in liquid, hold your finger over the top to trap a small amount, place it in baby's mouth, and release.
This is a good time to start straw cup practice. Use the dipping technique or try a honey bear straw bottle where you can squeeze liquid up the straw to show baby how it works. Many babies bite the straw at first rather than sucking, which is completely normal. Keep sessions short and pressure-free.
Most babies can master straw drinking with practice during this period. If your baby still struggles, continue practicing at meals. Some babies do better with shorter, wider straws or weighted straws that stay in the liquid. Straw drinking builds oral motor muscles important for speech development.
If your toddler still cannot drink from a straw by this age, keep practicing and consider trying different straw types. If your toddler also has difficulty with other oral motor tasks like chewing or making certain sounds, mention it to your pediatrician as a feeding or speech evaluation may be helpful.
What Should You Do?
When to take action
- Baby bites or chews on the straw instead of sucking
- Baby needs several weeks of practice to learn straw drinking
- Baby can drink from a straw sometimes but not consistently
- Baby is under 12 months and still learning
- Baby is over 15 months and cannot drink from a straw despite regular practice
- Baby also has difficulty sucking from a bottle or breast
- Baby has weakness in facial muscles or drools excessively

Related Feeding Concerns
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.
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.
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.
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.
