I've always read these threads in the past and decided not to stick my oar in since I'll no doubt be flamed, but this time I'm going to give my views.
I do judge those who choose to ff their children without even trying to breastfeed. I also judge women who smoke during their pregnancies and around their children. I also think it's a complete cop-out to state that ff works 'best' for their families and that what you feed your children is only a small part of parenting etc.
I was 18 when I found out I was pregnant. I was a single mother - DD's father vanished as soon as he found out I was pregnant. Nontheless, I immediately read every book I could find on pregnancy, birth and breastfeeding. I went to both NCT antenatal classes and NHS ones. I attended a breastfeeding support group whilst I was pregnant. I did as much research as I could about the birth process and made a birth plan. I endeavoured to make healthy choices throughout my pregnancy.
When DD was born, my milk didn't come in until day 6. Nonetheless, I had her on the breast virtually 24/7 and refused to cave into FF. Thankfully, my milk came in and I breastfed until she was 2.5 years.
Whilst I would have been devastated if my milk hadn't have come in and would therefore have to have FF, I cannot for the life of me understand why mothers would choose to compromise their child's health by not even trying to breastfeed. Why would you deliberately expose your child to a higher risk of obesity, diabetes, gastric illness, SIDS and childhood cancer? It's irrelevant whether some of these things can be treated by the NHS - why should the NHS have to fork out time and again for illnesses that could be prevented or at least reduced, through breastfeeding?
Why wouldn't a mother choose to put her own feelings about breastfeeding aside and make a determined effort to breastfeed her child? Surely everyone wants what is best for their children, especially health-wise? Why would someone deliberately ignore the mounds of evidence and cite the odd example such as "I was ff but it didn't do me any harm" in the face of such evidence to the contrary?
So, frankly, I do judge mothers that don't breastfeed because they simply don't want to. When you have children you have a responsibility to do the best you possibly can, not just what you feel like doing.
