First of all bullying is not helpful and not using common sense when caring for individuals is just ridiculous.
As a youngster I knew I wanted to breastfeed my kids after hearing my mom's stories who was quite a rebel in her day for insisting on nursing when she was at first advised it wasn't as good or enough.
I was not a nurse then, but read everything and also was advised it wouldn't hurt if you did it right. They lie. It is a big mistake for educators or writers to use their limited experience to pronounce such ridiculous statements. I nursed both of my kids for one year and both times there was a period of just pure torture until the nipples toughened up. I had a cheapo evenflo pump that was better than the painful grip of my newborns' mouths and would occasionally use it for a break.
I understand there are rules to keep baby friendly status, but if that is what drives someone to stop nursing, there is a problem. Why not use a good pump? Getting those antibodies into the baby should be of primary importance.
A few people posted here about formula becoming better and closer to breast milk. I doubt this. As time goes on, the value of breast milk is becoming more apparent. We are talking about life saving immunity! The newborn only has a passive immunity from mom and then the antibodies through breast milk so that whatever mom gets exposed to and develops immunity to, she passes on to baby. This became very real to me with my second child who was perfectly healthy at birth, then in serious danger a few weeks later. At week two the Dr told me she would not have made the recovery she did if I had not been nursing. These statements are not about shaming someone who doesn't or can't nurse; these are just facts that should be known.
