Why Experts Are Moving Away From Traditional Sippy Cups

Why don’t they recommend sippy cups anymore?

Sippy cups aren’t “banned,” but many pediatric feeding experts have moved away from recommending traditional hard-spout sippy cups as a default transition cup. The concern is less about occasional use and more about long-term, everyday reliance—especially when a child sips for hours or uses the cup like a pacifier.

One reason is oral development. Rigid spouts can encourage a sucking pattern that’s closer to a bottle than an open cup, which may limit practice with more mature sipping skills. Some children also keep their tongue in a forward position against the spout, which can interfere with learning the more efficient swallow pattern used with open cups and straw cups.

Another issue is exposure to liquids throughout the day. Leak-proof sippy cups make it easy for toddlers to “graze” on milk or juice, and frequent sipping can increase the risk of tooth decay—especially if the cup contains anything other than water. Milk pooled around teeth for long stretches is a common problem when kids carry a spout cup everywhere.

Finally, many classic sippy cups are designed to resist spills by requiring strong suction. That can frustrate kids, keep them stuck on sucking mechanics longer, and sometimes lead caregivers to enlarge valves or spouts, creating new choking and hygiene concerns if parts tear.

For many families, the more widely recommended options are a small open cup (with help) and a straw cup, which can support sipping skills while still being practical for day-to-day life. If a sippy cup works for your routine, choosing a softer, bite-resistant spout or a straw-style design and limiting all-day sipping can help address most of the common concerns.

FAQ

When should I switch from a bottle to a straw cup?

Many babies can start practicing with a straw cup around 6–9 months, with the goal of reducing bottle reliance during the toddler period. The best timing depends on your child’s readiness, daily routine, and guidance from your pediatrician.
