This premium glass bottle starter set gives you everything needed for smooth, comfortable feeding from day one. Two sizes—5oz and 8oz—grow with your baby, while four age-specific nipple stages adapt as feeding needs change from 0 to 6 months. The vented anti-colic design helps reduce air intake, making feeds gentler and more enjoyable for your little one. Made from durable glass and soft silicone, all pieces are BPA-free and built to last. Cleaning is easy too—bottles and nipples work safely in the microwave, dishwasher, boiling water, and sterilizers. One complete set includes two glass bottles, two extra nipple stages, and everything you need to start feeding confidently and conveniently.
