Philips AVENT SCD201/01 Natural Glass Newborn Starter Set is the most natural way to start bottle feeding. The 5 BPA-free Natural bottles included in this kit feature wide breast-shaped nipples with unique comfort petals promoting natural latch on and making it easy to combine breast and bottle feeding. The bottles have an advanced anti-colic system with innovative colic-reducing valve designed for less air in baby's tummy and a more comfortable feeding experience. The soft, flexible nipple mimics the feel of the breast. The set includes 3 Natural glass 4 ounce/125ml bottles with 3 Natural newborn nipples, 2 Natural glass 9 ounce/260ml bottles with 2 Natural slow flow nipples, 1 Bottle sleeve to protect and insulate, and 2 Soothie silicone pacifiers (0-3m). The Soothie pacifier is used by hospitals to calm newborns and feature durable, hospital-grade silicone and one piece construction.
