Awkwardness around discussing infant feeding is a tale as old as time. Whenever breastfeeding is discussed/posted about there is always the whatabouttery around FFing. No woman should feel silenced or like they cannot post about how they feed, all choices/circumstances should be respected so that however women feed there's no 'guilt'. Formula feeding is amazing, I did it for various reasons and yes it did affect me and took me a while to come to terms with, but breastfeeding is also amazing. If she had posted with a bottle would she be seen to be braggy? Or would it just be ah she's feeding her daughter- why can't can't both be normalised and respected? We have one of the lowest rates in the world, which is fine if its genuine choice not to; but often its that there's not the support, or it's something someone has considered because it's not often spoken about. I don't think she is bragging about it, just posting about it. I suppose you could say anything someone posts about is braggy I guess.
Anyway, let's celebrate all women, however they feed, and not police their bodies.
