3-in-1 Stainless Steel Sippy Cup | 250 ml

The last sippy cup you'll buy for your child. Independently lab tested, developmental stage by stage, built from platinum-cured silicone and electropolished stainless steel.

The Only Baby & Toddler Cup You’ll Ever Need

There is a certain frustration in the mismatched clutter that accumulates in every parent's cupboard, a collection of leaky plastic bottles, each for a slightly different stage, and none of them built to last. We wanted to end that cycle. Our 3-in-1 Stainless Steel Transition Cup is the only bottle your child needs, designed to evolve from those very first sips at six months old through to the busy toddler years.

The Leak-Proof Transition Cup for Every Stage

The transition cup that grows with your child. This plastic-free upgrade features a redesigned leak-proof sippy lid for beginners, a leak-proof straw lid for active toddlers, and a clever valve straw for on-the-go adventures. Designed with oral development in mind, our straw lid supports mature swallowing patterns. Read our guide on why speech pathologists prefer straw cups over hard spouts. When your little one is ready for the final milestone, simply remove the lid to graduate to a big-kid open training cup. One durable, unbreakable cup for every developmental leap.

Designed with Development in Mind

Beyond being practical, this cup is designed to support your child's physical growth. Moving from a spout to a straw and eventually an open cup is a journey that supports healthy oral motor development. By encouraging the lip and tongue strength needed for clear speech and confident swallowing, we’ve made sure that the "healthy choice" is also the easiest one for parents to make. Not sure when to switch from the spout to the straw? We have summarised the American Academy of Pediatrics (AAP) and Raising Children Network guidelines for you. View the Sippy Cup Development Timeline here.

Whether it is a morning smoothie or water on the bedside table, this non-toxic sippy cup is a reassuringly sturdy, shatterproof essential that prioritises your child's health and our planet's future.

The Transition Essentials

• True 3-in-1 Versatility: Easily adapts from a soft silicone sippy spout to a toddler straw cup, then finally an open training cup.
• Premium & Safe Materials: Crafted from electropolished 18/8 food-grade stainless steel and FDA-certified BPA-free platinum silicone.
• Encourages Speech Skills: Straw and open-cup drinking are widely recommended by health professionals for building the oral strength needed for clear speech.
• Practical for Busy Days: Completely dishwasher-safe and lightweight enough for small hands to carry independently.
• Dignified Design: The easy-grip handles also make this an excellent, non-slip choice for aged care or assisted drinking needs.
• Calming Colour Palette: Available in four beautiful, earth-inspired shades: Peach, Sage, Cream, and Cocoa.

Recommended from 12 Months: Designed for toddlers who are ready to transition from a bottle. At 6–12 months, babies are naturally inclined to pull and push with force. From 12 months, the cup comes into its own as little ones develop more intentional drinking habits.
