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.

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.

Constant flow prevents colic
