I am sick to the back teeth of hearing these reports. We get it!
Raising a child into adulthood, to the age of 30 in the study, takes more than breastmilk and there will be:
a) so many twists and turns on their path to adulthood
b) different factors in their lives that will influence their outcomes
It is impossible to genuinely identify breastfeeding as single factor that will guarantee a high IQ and higher earnings.
Not every mother can breastfeed. It does not make them a bad mother. Genetics, parental support, siblings, childcare arrangements, health and wellbeing, being a carer, stimulation, play, downtime, postcode, friendships and peer group, educational attainment, schooling, careers advice, interests/abilities et cetera... all come into play.
Article in the Guardian today "Bright pupils more likely to fall behind if from poor background, study finds". One of the key points made is that students from poorer backgrounds were less likely to choose "facilitating subjects" than wealthier peers.
Besides, higher IQ and higher earnings doesn't automatically equal happiness. I've seen many friends, high performing ones in well paid jobs have stress meltdowns. I also know someone who can barely write, but he'll have more money in the bank than I ever will. So what.
But what really pees me off
, is seeing things like this happen to kids: www.mirror.co.uk/news/uk-news/horror-pictures-reveal-filthy-home-5346598
It doesn't matter whether a baby is bf or ff. What matters is they are loved and cared for, to be happy and the best that they can be.
