We are starting to set up our registry (Grandparents and great grandparents have been begging for one already!) and one thing I am unsure about is bottle warmers. I hear all the time they were a waste and completely unnecessary, which I would TOTALLY agree with if we were planning of doing formula. I plan on BF and pumping though, so is it a necessity for pumped milk? How do you warm yours if you don't use a bottle warmer?

Advice? Suggestions?
