sycamore, it's OTT to be 'outraged' at what I said. Of course it is a 'clinical decision' to give formula to a breastfed baby. It is an intervention, to be made on clinical grounds i.e. on grounds related to health. If a baby is not being adequately fed, and breastfeeding cannot be improved to make it adequate, then of course it is a 'clinical decision' to use formula....'clinical decision' does not have to mean medication or surgical treatment, it can mean any sort of decision related to health or well being.
If a mother decides she wants to use formula, and the HCPs who are caring for her decide this is not clinically necessary ( that is - and sorry, but it appears to me I have to spell out to you what to others might be common sense! - the baby's health and/or the mother's health are not enhanced by its use) then of course she should not be prevented from using formula. But she cannot 'demand' its supply, any more than she can demand extra snacks for herself at 3.30 pm, or demand a lace bonnet for her baby, or if we are talking clinical assessment, she can't demand treatment for imagined jaundice or tell the HCPs her baby is constipated and needs laxatives . If she wants these things, she can of course supply them herself (prob not the jaundice treatment).
The majority of women will be able to get formula if they want it. If they have no one, literally, to get it for them, and still feel very strongly they want it, most postnatal wards would supply some alongside encouraging her to sort this out for herself .
You say, "Even if the baby is being fed adequate quantities of breast milk, all that will happen if the parents offer formula is the baby will refuse it or will spit up excess". No. This may happen, but it is not by any means the only thing that might happen either in the short, medium or long term. Giving formula to a BF baby is sometimes necessary, but it should not be a casual decision.
You say , it is " a power trip by undertrained and misguided personnel to deliberately deny a helpless infant food".
Ridiculous exaggeration and dramatic overstatement.
"if the mother wants to supplement with formula, why would or should the midwife have any veto over that decision? ". But she doesn't have a veto. Fortunately, this decision rests with the mother, who remains able to choose to supplement, unless she is literally alone in the world and somehow chained to the postnatal ward bed with no Contacts with the outside world. If a mother is literally in that position, and is very sure she wants to give formula, then the scenario I have suggested above applies.
