Playtex Drop-Ins System
With my 2 1/2 year old, we tried nearly every bottle on the market before he settled on the Avent bottles. They were great, but I'm thinking with the next one (due in a couple weeks), I would like to use the Playtex Drop-Ins. But my question is this... To those of you who have used these, how do you warm the milk or formula? Microwaving is always a no-no, and with the other bottles we've used, we heated the contents with a bottle warmer. These say not to put the bottle into a heat source. Do I have to heat it in a separate container...
