We love simplicity. We don’t love chords or batteries or anything else that may make life with kids more complicated. Our On-the-Go Bottle Warmer is a simple way to be prepared for a hungry tummy on the go. Press a button to warm the heating pouch and boil it in water to re-use it. It’s that simple. No wonder it is has been a family favorite travel bottle warmer for decades.
