Parent's Choice BPA-Free Standard Neck Bottles are made of FDA-approved food-grade polypropylene and silicone, making them safe to use for babies. This three-count pack of 9-oz baby feeding bottles comes with slow-flow nipples that are soft and vented to promote natural feeding and help prevent the baby from ingesting air that can cause indigestion and excess gas. Parent's Choice bottles are designed to prevent the nipple from collapsing during feeding, allowing the contents to flow freely like natural breastfeeding. They also feature a secure cap that keeps the nipple clean and reduces leaking while traveling or storing them. Microwave and dishwasher safe when placed on the top rack. Suitable for newborns and age group from 0 Months and up. Multicolor in neutral shades.
