Oh do fuck off Stinkers. I really felt for the author of that piece because I've been there too.
What you do when you're confused, sleep deprived, completely thrown by conflicting advice and struggling to breastfeed is not necessarily what you'd do in your usual state of mind.
My DS lost 15% bodyweight and was readmitted to hospital twice. I was desperate to breastfeed as it had been so drummed into me that I HAD to.
I pumped round the clock, til I was hallucinating (yes, really - I thought I was producing containers of milk and it was a kindly midwife who told me she couldn't see anything).
I tried every bloody position, I found an independent lactation consultant, I listened to the earnest NHS breastfeeding helper who arrived at my bedside with a knitted boob and a fucking Tiny Tears doll, as if that would help.
All I wanted was the best for my son. I listened to all the rhetoric about him only needing a tiny bit of colostrum in the early days, about bf babies taking what they need. I could both see and not see that he was shrinking before my addled eyes.
I needed strong advice and support, I got none. I genuinely wanted to kill myself when I "caved' and bought Aptamil as not one midwife would tell me I was doing the right thing.
I didn't know what to do. Frankly, your being "rather angry" at the author of that piece and perhaps, by extension, mothers like me who faced the same struggles, is a bloody insult.
Why don't you take that "anger" and direct it towards the patchy and inconsistent antenatal care we have in this country.
