I think this is so great!! Obamacare may have it's flaws, but this is a great benefit.
I fear that some insurances will give a hard time if the doc does not "prescribe it" or say it's medically necessary (like you have a normal newborn and not a premie (most insurances already cover one for premies)) - BUT in my experience, any doc would do the documentation needed to get it covered for you.
Also - I wonder what's "covered" - if they're going to start shelling out breast pumps, I fear they may not be the best quality (not that everyone needs "best"- it totally depends on your needs - I was just fine with my single manual with Lillian, but with Amelia I upgraded to a double Medela and OMG - what a difference!) Any way - just my random thoughts about it. haha
