Breast feeding is easy and natural. Please stop listening to those idiots who say it is hard. Just whip it out.
Beware doctors. They know very little about BF'ing and most of it is wrong.
Sheila Kitzinger writes about breastfeeding, and it was very helpful. In essence, take off your shirt and go lay down with the baby.
I started back to work at 6 weeks for each of my three kids. One is still nursing at 6 month, another had more than two years, and the first had more than a year. BF'ing makes baby care easier. I just throw a diaper in my purse, and we're off.
Hang in there, you're doing great. Just remember we all make different choices about parenting. Have confidence in your choices.
