Agree about the 'luxury' bit. In the old days, richer women didn't breast feed, they gave the job to wet nurses.
I went through intense pain persevering to breastfeed.... never mind the social and professional costs of sustaining it, and the joys of being bitten once she grew teeth! I don't regret it. I am proud that I did, but it was one of the hardest things I ever did (the first month's pain part).
On the other hand, he isn't dissing breast feeding - he is saying 'don't make others feel bad who can't'. And I do agree with that. The social judgement on women if they don't breastfeed is strong.
When I was going through so much pain struggling to feed, some of the pain was emotional - shame based. I felt like I wasn't a full woman and was failing as a mother if I wasn't feeding my child that way. Another friend of mine just didn't have enough milk, and she wouldn't let her baby supplement because she had it so strongly implanted in her that she had to fully breast feed her baby. The baby was underweight for months, and I think consistently hungry, but nobody could persuade her.... she was driven by a sense of shame if she succeed in nourishing her child from her breasts.
If we can promote breastfeeding without imposing shaming of women when they can't, I am all for it.
