The Original touch glass Feeding Bottle comes with a soft rubber teat made from natural rubber of plant origin, and provides a warm, natural feel that resembles the mother's skin. This makes it easily accepted by your baby for an easy switch between bottle and breast feeding. The teat also comes with an anti-colic valve that prevents the ingestion of air, reducing colic and discomfort after feeding. This elastic teat is highly durable and resistant, and the milk flow rate suits your 2 month old baby's needs and older. The bottle also comes with a protective cap that keeps it clean when not in use.
