Hi Wheatie - I used the Avent shields (they come in at least 2 sizes, btw, so try to buy the one most like your nipple (very amusing pharmacy experience!)). I only used it on one side, and when DD was about 4 months old. Suddenly my let down on one side got really "fierce", and would freak her out. I read in Sue Cox's "Breastfeeding with Confidence" that shields can slow down flow, so used them for a few weeks to great effect.

Early on, I used Lansinoh cream religiously (you can BF with it on), and nipples stayed supple and pain free.

Best of luck - sounds like you are going to be well prepared and supported - ABA are great!
