We all know breast feeding exists though :s
But not many women in certain areas consider it a realistic option. It's something that 'posh' women do, not people from council estates. You'd also be surprised at how many people don't think BFing is actually enough to sustain a baby longterm. Many women in the 60s and 70s were taught that breastmilk isn't adequate after 6 weeks/4 months/6 months (I've heard various random times given).
Formula is culturally normal. Bottles are the symbol on nappy change rooms. Babies with bottles are often portrayed on TV shows. There is an advert now showing a bottle being warmed in a bowl of hot water as a short hand for how 'we all use energy everyday'.
The fact is, a tiny amount of women are actually breastfeeding for any length of time, especially exclusively. If breastfeeding was anywhere near the majority infant feeding method, then I'd agree that penalising those who formula feed because of medical reasons or just because of work commitments or whatever, is massively harsh. But the fact is that breastfeeding has a lot of ground to make up.
I think the policies of the NHS are wrong. As I said, posters and midwives forcing a nipple towards a newborn baby are not good enough 'support'. There needs to be investment in BFing services and support networks, training so GPs don't suggest a top up if LO gains 2oz one week rather than the 'average' 7oz. HVs who don't suggest a formula bottle to help baby sleep through.
However, keeping formula companies on a tight lead is absolutely the right policy IMO. Just look at their conduct in countries where there isn't any protection, and you'll understand why they need to be kept in check by law. Even here, they try and get around the legislation.
