Frequently asked questions

What's the difference between a straw cup and a sippy cup?

Straw cups encourage a mature swallowing pattern and are recommended by many speech-language pathologists over hard-spout sippy cups. Our cups use a soft silicone straw or tip — a gentler alternative to traditional valved sippy cups.

When can my baby start using a straw cup?

Most babies are ready to learn a straw cup around 6 months, alongside the introduction of solids. A weighted straw helps because it draws from any angle, so the cup works however your baby tilts it.

Are PPSU and stainless steel cups safe for babies?

Yes. PPSU is a hospital-grade plastic that's BPA-free and BPS-free, and our stainless steel cups use food-grade 304 steel. Both avoid the chemicals parents most want to keep away from their babies.
