I loved my cheapo medela one last time and this round I got the more expensive upsie belly. I am not sure if it was that or just how it was but I didn't have to wait all that long for my tummy to pull back up and I noticed no after pains.
I used a back pack a lot, especially when going anywhere I was going to be walking a bunch. It even can help you feel more balanced. I got one I really liked from ll bean with enough pockets for my things to be easy to find.
