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.

Tip: We advise you squeeze the valve several times before each use to make sure that the tiny air hole in the centre of the valve is open.
