Formula babies are not malnourished far from it. What a hideous inaccurate statement.
My babies were malnourished when bf, formula nourished them.
Re intelligence I remember evidence showing previous data re intelligence and bm being discredited a while back. Intelligence is very hard to base any stats on as bf babies are far more likely to have healthy eating mothers and mothers more likely to stimulate said baby.
The debate was always over 3 points or so big whoop,3 points could go up or down either way.
Also my mothers family has a long history of ff,no bm what so ever.My grandmother's kids went to grammar school,uni then were teachers and one is a medical scientist. None have any health problems what so ever.
My dad's mother bf all hers for ages,only my dad went to uni and he had several allergies,food intollerences.
I was bf,my sister wasn't at all.My sister got into a top Russell group uni (I went to a poly)and has written books and is v successful in her field.She has no allergies.I have sensitive skin,fertility probs.
Any sane person accepts intelligence and health are down to genes,healthy living and life opportunities.6 months of bm makes buggar all difference in the grand scheme of things however much you chant breast is best(which nobody actually disputes).
