The Thinkbaby Bottle-to-Sippy Conversion Kit (Pink) is designed for a smooth transition from bottle feeding to sipping. The kit fits Thinkbaby 5 oz and 9 oz baby bottles and converts them into no-spill sippy cups using a soft, cross-cut medical-grade spout—perfectly suited for babies aged 9–36 months. This BPA-free, dishwasher-safe accessory reduces both environmental and financial waste by eliminating the need to buy separate cups when babies advance past bottles. It’s a simple, convenient, and eco-friendly solution to extend the life of your baby bottles.
