Going back to my previous post (someway down this thread!) and to answer Caligula's question - dd2 was breastfed on demand. Now, I am assuming, because no-one actually told me, that the reason she was dehydrated was because my milk had not come in after 4 days.
Maybe colostrum alone was not sufficient for length of time - I don't know. Maybe the latch wasn't quite right. Maybe the fact I suffered a pph had some impact. The whole point is, I was a 2nd time mum who had successfully breastfed her first dd, and I was feeding on demand, and dd2 still ended up with jaundice and dehydration.
I do know though, that if I had been advised to give formula I would most likely have kicked against it because I'm bloody-minded, but, the whole experience was hell because they gave her a lumbar puncture and pumped her full of antibiotics just in case she had meningitis, so if I had been told that giving her one or two bottles of formula whilst I was waiting for my milk to come in would have prevented the whole thing, then, yes, I would have done it.
Not saying that the article isn't full of holes though .
