I got my breast pumps (yes, pumps!) today! I sort of love this "insurance pays for pumps" thing because I got two Medela PISA's for $10 in shipping

I do have a question though...the breast shield/flanges - is it possible you may have two different sizes? I will ask a LC too but wondering if anyone knows?
Re: It was like Christmas at my house!
Your nipple should move freely within the flange, without rubbing against the sides, and without much areola being drawn into them.
Also, I can't believe how looking at a bottle makes it all so real! I was just telling DH we need to find all of our bottles and baby stuff and here I get this box today!! Suddenly I'm more excited!

Depends. That often does mean that your flange is too big. Do you feel sore after pumping? If you're having trouble figuring out whether yours fits, you can stick a flange in your hospital bag and ask the LC about the fit after you deliver LO.
It's important to have the best-fitting flanges both for your own comfort and for pumping efficiency. You'll have a better yield and your supply will be better maintained with a well-fitted flange.
