Fedup, you say:
" but being a bottle feeder I didn't need to use a breastfeeding counsellor and didn't need help with feeding whilst on post-natal ward so I used less NHS resources.
It probably evens out. "
No it doesn't, sorry. On an individual level, no one can say, but in public health terms, there is absolutely no doubt that less formula feeding would mean a great deal less cost to the NHS. If you are unconvinced, I can give you references.
"....any more than higher taxes on booze and fags have decreased the number of smokers and alcohol related medical problems."
In fact, the higher cost of tobacco and alcohol is one of the few measurably effective "anti" measures. But this sort of punitive taxation is not appropriate when it comes to infant formula, IMO.
" I lost touch with her when I returned to work. Imagine my surprise to meet her again 2 years later and see the poor quality food she is now allowing her kids to eat on a regular basis."
That's judgemental and assumption-jumping, fedup, unless you actually live with this mother and know what she does every day. If she does give her kids poor food, then it's a good job she breastfed, then, as it has been shown to reduce inequalities in health, including the inequalities exacerbated by formula feeding.
