I bought Libra and only bought 2 packs before I had DD1. I only used them for a few days and then went onto normal pads. I didn't even buy anymore when I had DD2 because I still had them left over, lol. So you don't necessarily need to buy heaps! I never used two at once either, I think they pretty much reached from one end of my undies to the other they were that long.

But definitely ones with wings!!!! And buy some plain black undies.
