I think I'm the only one who might be going through their first kid - maybe it'll help some lurkers.
I just called my insurance and found out I have 100% coverage for electric breast pumps through any in-network durable medical supply and I can get up to two per year. So I can get one for work and home, which I was dreading lugging that thing every day back & forth on the train and long walk. I may be overly excited about my boob milkers 
So call your insurance and find out if you have any coverage. It's nice to take it off the registry and not have to worry about it!
