When I was pregnant, I was concerned about not being able to get a pump prior to birth. I spoke to a lactation consultant friend of mine, and her take on the matter was that if I really needed a pump in the early days, I should probably be renting a hospital grade pump anyway, not an insurance company pump, since the hospital grade ones would be much better at helping with the kinds of issues that happen early on, and would be able to yield a lot more milk and keep my supply up better. This reassured me so I just went ahead and ordered the insurance company pump after my son was born, and figured I'd rent a hospital pump if I needed one sooner (which I didn't!).
