You can introduce a straw cup as early as 6 months, when your baby starts eating solid foods. The American Academy of Pediatrics and the CDC both note that this is an appropriate time to offer either a spouted training cup or a cup with a straw. Most babies need some practice before they get the hang of it, but 6 to 9 months is the sweet spot to begin.
Why 6 Months Is the Starting Point
Around 6 months, babies develop the basic oral motor coordination needed to start learning new ways of drinking. They can sit with support, bring objects to their mouth, and are beginning to move their tongue in more complex patterns. Straw drinking requires a specific skill: the tip of the tongue lifts to the roof of the mouth, creating a wave-like motion that pushes liquid backward for swallowing. This is different from the suckling motion used during breastfeeding or bottle-feeding, so it takes practice.
That said, not every 6-month-old will take to a straw right away. Some babies pick it up within days, while others need weeks of exposure. The goal at this age isn’t mastery. It’s familiarity. By 9 months, most babies can also begin practicing with a lidless open cup, though that’s messier and requires more hand-eye coordination.
Signs Your Baby Is Ready
Age is the starting guideline, but your baby’s behavior tells you more. Look for these cues:
- Good lip closure: Your baby can seal their lips around a spoon or toy without liquid dribbling out constantly.
- Sitting up with minimal support: Drinking from a straw works best when a baby is upright and stable.
- Interest in what you’re drinking: Babies who reach for your cup or watch you drink are often ready to try themselves.
- Tongue movement beyond suckling: If your baby is moving food around in their mouth during solids, their tongue is developing the coordination straw drinking requires.
If your baby can’t close their lips around the end of the straw, they may need a little more time. Some parents find that coating the tip of the straw with a favorite puree encourages the baby to close their mouth around it.
Why Straw Cups Beat Sippy Cups
Pediatric dentists and speech therapists consistently recommend straw cups over traditional spouted sippy cups, and the reasoning comes down to tongue position. A hard sippy cup spout sits over the front third of the tongue, holding it flat and preventing it from lifting. This mimics the infant suckling pattern babies are supposed to outgrow.
When toddlers keep using that immature swallow pattern, it can make chewing and swallowing new food textures harder. A tongue that can’t elevate tends to rest low and forward in the mouth, which can interfere with speech development over time. Speech-language pathologists have noted that overuse of the suckle-swallow pattern promotes this forward tongue posture.
Straw drinking, by contrast, requires the tongue to lift to the roof of the mouth. This is the same position needed for a mature swallow and for producing many speech sounds clearly. It also supports better jaw development, since proper tongue positioning during drinking influences how the jaw grows. Once your child has gotten comfortable with a straw, you can trim the straw shorter so just the tip reaches the tongue when their mouth is closed around it. This ensures the tongue continues to elevate rather than reaching forward.
How to Teach Straw Drinking
Babies don’t instinctively know how to draw liquid through a straw. They need to learn that sucking on a straw produces a result. Two techniques work well for this.
The Pipette Method
This is the simplest approach and requires nothing more than a regular straw. Place your finger over the top of the straw to trap a small amount of liquid inside. Bring the straw to your baby’s mouth and wait for them to open up. Once they close their lips around the bottom end, release your finger. The liquid drops into their mouth, and your baby starts to connect “straw in mouth” with “liquid arrives.” Repeat this several times per feeding session until they begin trying to suck on their own.
The Squeeze Cup Method
Honey bear cups and similar soft-bodied straw cups work on the same principle but let you be more hands-free. You place the straw in your baby’s mouth and gently squeeze the base of the cup, pushing liquid up through the straw. The baby learns that the straw delivers liquid without having to generate suction themselves. Over multiple sessions, you squeeze less and less, encouraging your baby to do more of the work. Pairing simple language with the action (“here comes the water!”) helps build the cause-and-effect connection.
With either method, keep your baby’s chin neutral or slightly tucked downward. A head tilted back increases the risk of coughing or gagging. Start with water or breast milk in small amounts so any spills are low-stakes.
What to Expect at Each Stage
At 6 months, most babies will chew on the straw, let liquid dribble out, or look confused. This is normal. You’re planting the seed. By 7 to 8 months, many babies start getting small sips successfully, especially with the pipette or squeeze method. Around 9 to 12 months, straw drinking typically becomes more coordinated, and your baby can take consecutive sips without losing most of the liquid.
ASHA’s revised feeding and swallowing milestones, updated in 2023 and 2024, represent the ages by which at least 75% of American children have mastered specific skills. Individual variation is wide. A baby who isn’t interested at 6 months may take off at 8 months with no issue. Consistent, low-pressure practice matters more than hitting an exact date.
Choosing the Right Cup
For beginners, look for a straw cup with a short, soft silicone straw. Shorter straws require less suction, making them easier for new drinkers. Weighted straws that reach the bottom of the cup let your baby drink at any angle, which reduces frustration. Cups with handles are easier for small hands to grip independently.
Avoid straws that are too long or rigid, since babies tend to gag on them or push them away. Some straw cups designed for young babies have a textured or bumpy straw tip that provides sensory feedback and encourages babies to close their lips around it. If your baby keeps biting the straw flat instead of sucking, a firmer silicone tip may help them learn the difference.
As your child gets more skilled, you can gradually move toward regular straws and open cups. The straw cup doesn’t need to be a permanent fixture. It’s a bridge between bottles and independent drinking from a regular cup.
