Our Natural glass baby bottles combine premium borosilicate glass with thoughtful design to support your feeding journey. Each bottle features a soft, breast-shaped nipple that mimics natural breastfeeding, making combination feeding feel familiar and comforting for your baby. The intelligent no-drip flow system prevents spills and lost milk whether you're at home or out and about. An integrated anti-colic valve keeps air away from your baby's tummy during feeding, helping reduce discomfort and fussiness. The durable borosilicate glass is completely BPA-free and safe for refrigerator storage, warming, washing, and sterilizing. Your baby controls the milk flow pace just like with breastfeeding, giving them a natural feeding rhythm. This set includes two 8-ounce bottles with medium flow nipples, perfect for establishing a comfortable feeding routine that works for your family.
