Yes! Your Ceres Chill is incredibly versatile and can be used to warm baby bottles on the go. Just put hot tap water in the outer chamber and seal it up as usual. Then when you are out and want to warm milk or formula, just pour the cold milk/formula into the empty inner chamber by unscrewing the cup and small cap. Close it all up. Wait 4-6 minutes and then pour the warmed contents into your favorite baby bottles. Rinse out and repeat for up to 3 bottles in 10 hours.
