Query: Takes too long!

I registered for one of these bottle warmers and I never even used it one time! Honestly, by the time you are up at 2:00am and your baby is screaming the only thing you want to do it pop a bottle in the microwave and get back to your child ASAP! Once you establish a time on the microwave, it is much easier and faster to use that than the bottle warmer. Also when warming breast milk I ran it under warm water, so the bottle warmer didn't work for that either! Some people might like bottle warmers,but for me it was a waste of space on the counter!
