But Twinkie - it is the woman's RIGHT to choose what is best for her - whether BF or fomula. It is no one else's right to tell what she should do. Advice if she wants you to but you shouldn't push your own opinions on anyone else.
If she is not happy with BF'ing that BF'ing is not the right decision. Baby will only be happy is mum is. And there is so much more to a baby's happiness and health than simply feeding alone. What about love, nuture, care, safe home, happy family life, healthy diet of mum, non smoking household, no drugs around, clean places to play and sleep, no neglect, etc. Surely many of these are just as importnat and some more so?
Yes, I know BF is nutrionally better for a baby but not always pschologically for mum (and therefore baby too). It has to be weighed upsurely. Formula is not the devil's work.
I know children who have been BF and formula fed and there is no difference IME of any differences between them. DH and BIL were completely bottle fed and have never had ANY problems in life - have no health issues, no allergies, no exzcema, etc. I was completely BF and have hay fever, psorasis, and heart problems. This is just one example of many I can cite. It is things like this that cause mums to feel so guilty unnecessarily.
