S Bottle Valve – 2 pack
The Difrax Anti-Colic Valve (2-pcs) for the S-baby bottle is integrated in the removable base of this popular baby bottle. The valve provides a constant, regular flow of formula or breast milk and prevents stomach and intestinal cramps, reflux, burping and colic. Routinely replace the soft, silicon valve as you would the teat. We recommend that you change the valve and the teat every 6 weeks if used on a daily basis.
