Smokering, I have the same shirt drenching problem! Pumping and bottles will be a necessity for me because I'll be in school. But even if I weren't, I think I'd still pump so that I could have some times away from the baby here and there. After a while it starts to feel rather stifling to not be able to EVER be away from the baby. Or to time outings without baby between feedings.
Have you seen the Human Milk 4 Human Babies Facebook pages? It used to be called Eats on Feets, but they changed their name a few months ago. There is a global page, and then tons of pages for different countries and US states. There is a vast network of milky mamas that are sharing milk and wet nursing babies all over the place. It's so cool!
I'll be donating some of my milk, assuming that I'll have extra that I don't need, to mamas in my area that need it. I pumped exclusively for my birthdaughter for 4 months and she had breastmilk for 6 months. I was getting 50 ounces a day at one point. Of course, I don't expect to have that much milk stored up this time around because I'm nursing a baby and pumping at the same time. But I've never had issues with undersupply so I'm hopeful that I can feed my baby and help feed another one as well.
