The Difrax Anti-Colic Valve (2-pcs) for the S-baby bottle is integrated into the removable base of the popular baby bottle. The valve fits all the Difrax bottle sizes and  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 to squeeze the valve several times before each use to make sure that the tiny air hole in the centre of the valve is open.
