The only thing that worried me was to do it in public, at some point the baby would be hungry and I couldn't avoid to breastfeed her in public, then my mom told me to use cloth diapers to cover me while I get used to it, because although it is natural and magic it's also uncomfortable flashing your boobies everywhere, or at least it is for me.
After Alice was born, I realized that this was the least thing I ought to worry, but rather I had to prepare for the pain I felt trying to breastfeed. First the milk didn't low down when it was needed (people told me it happens when you give birth by C-sections) so I had to give her formula for three days while she learned to latch on properly to produce milk on me, but she was so lazy that it cost me more than three days . I tried everything, hot towels, I comb my breasts (yes, comb), drank malt and oat beverages until God knows when, and finally my breasts filled BUT that's not the end, then when I was finally ready to nurse her I discovered I had plugged ducts so that the milk didn't come out, Alice tried to eat but nothing came out. My breasts were to burst at anytime, with the help of a breast pump it opened gradually. In the end, breastfeedind cost me blood, sweat and tears but it was all so worth it.
Now my baby is 8 months and only takes one bottle every day, at night to sleep, she has given a flu just once and thank God she's been very healthy. Being a mother is a miracle of God and to feed your baby in your own body is magical.
I feel comfortable breastfeeding in public, discreetly, of course.
So to you all mothers-to-be, who are thinking about it I can tell you: It's worth all the pain, is something that you wont regret.
