I couldn't breastfeed, and it took a long, long time to come to terms with that. I don't recall being judged by anyone but me either when I was trying to get breastfeeding to work, or when I was bottle feeding. I have absolutely no doubt that it happens in both directions. I was by far my worst critic though. I have no idea why I feel the need to give my baby-feeding credentials before posting an opinion here, but anyhow.
To me, the point of the advertisement wasn't 'breastfeeding vs. formula feeding', but was 'Use SMA/Aptimil/Cow and Gate, it's better than Cow and Gate/SMA/Aptimil'. I can see why they have to tread very carefully around breastfeeding, but part of me thinks that they're going for the captive audience of people who through choice or necessity have already chosen formula, and then trying to make them feel most comfortable about their decision.
Anyhow, to be honest I find I feel equally nauseated by most baby-related adverts. The Johnson's one 'when a baby is born, purity is born' makes me want to boak. It makes no sense. If the baby was that sodding pure, there would be no need for cleaning products at all. They're not pure though; they're pukey and pooey.
Maybe it should go 'when a baby is born, you'll suddenly realise that you're going to be elbow deep in poop and sick several times a week. Tempting as it might be, don't use Domestos - Johnson's is a much better option for your baby's skin.'
