Sounds like you really needed support Meow. I was told with my first. Feed him every 4 hours, that was almost 8 years ago but it was never going to work. Babies need to be fed on demand whether bf or ff.
With ds2 I went to see the HV panicking because I'd switched to formula and his poos had turned all green and horrible.
I was saying I wished I'd just kept trying to bf but my milk was gone (I could have got it back), I was asking if there was a difference in formula brands. Literally all he kept saying (male health visitor), was "it's cows milk, it's cows milk", and shrugging. Then he told me to make sure I was making it up within the legal guidelines. The LEGAL guidelines. I think he meant by the instructions on the tub. I knew how to make a bottle properly and safely.
I didn't know about reflux, cows milk intolerance. I didn't realise babies could react badly to formula.
I'll admit I knew breast was best and protected against illness but I didn't realise quite how important it was. It sounds so naive but no one in my family has ever had any allergies to anything.
We eventually switched formula which did make a difference.
Ds probably would have had reflux anyway, my dh did as a baby despite being bf, and ds was 'sicky' from the start.
I think women do need to understand fully what formula is because if everyone around you uses it it kind of doesn't register.
Women do need other guidance on formula feeding beyond just following the instructions on the tub as Meow has said.
