Thanks to the Bib'secondes Patented steam heating system, you can warm baby bottles in less than 2 minutes and baby food jars in less than 5 minutes. The precise timer guarantees the correct temperature so you know it's safe for baby. Dual Programming on the Bib'secondes allows you to select the starting temperature of foods (either from the refrigerator or room temperature) and the amount of liquid or food you are warming. Once heated, it safely keeps bottles or jars warm for up to 10 minutes.
