I found this article interesting although I disagree with the conclusions
It is a policy paper (ie polemic/ opinion) not really a research based review although some findings are referenced it is not intended to be balanced.
The overall idea seems to be that government should cease to interfere in mothers individual choices as there is insufficient justification to do so on a public health basis and it causes distress.
The government intervenes in individual choices to a greater or lesser degree for health reasons all the time eg smoking ban, change for life campaign. The question then is whether this issue is important enough to justify intervention. She says there is not enough evidence of health benefits but I would like to have seen more consideration of the evidence as this is her key point. Short term benefits eg reduction in Gut infections are well established. Long term is harder to establish just by the nature of enrolling to long term studies and confounding factors.
I don't think many people would care about a few IQ points but if there is an effect on obesity that would be really worthwhile from a public health POV. I think it is plausible there could be but don't know if there is good evidence.
Her point about perceived pressure to bf is less convincing as there is also pressure on women not to bf in different sectors of society or at different times eg post 6 months.
My take is that bf is the default option. That's just a biological fact. Formula is an intervention that needs to be justified. A woman may consider it is justified in her own individual circumstances for many reasons including social/ psychological ones and that is fine but the starting position should be bf.
