Meet Rosie the Roo, an Australian-designed natural rubber teether that brings a little adventure into your baby's world. Rosie engages all five senses through gentle contrast details, natural rubber texture, a subtle Hevea scent, thoughtfully placed chew zones and a soft squeaker, creating a comforting, sensory-rich experience for little hands and mouths. What's revolutionary about Rosie is her mould safe design. She has a fully sealed squeaker so that you can stimulate hearing without the risk of mould build up inside.
