I don't watch Corrie, but in general, soaps are lamentable at portraying the issues surrounding bf.
I think it's a great opportunity missed, really - but it's like all the newspapers and parenting magazines out there that are so often full of articles that work through the author's issues with bf/not bf, all carrying advertising from formula/bottle/teat manufacturers - it's biased, bf isn't seen as important enough to warrant a concerted campaign; formula's "the same" as bmilk, and, of course, you "mustn't make women who can't bf feel guilty".
That last spectacularly misses the point that if more women were empowered and educated better about bf in the first place, there wouldn't be so many feeling guilty. AND anyway, why feel guilty that you were let down by the people who were meant to be supporting you. ANGRY, yes, guilty, no.
On EastEnders, Roxy breastfed Amy - well, she expressed for her in SCBU and much was made of how good bmilk was for Amy, how she was pumping regularly, etc.
And then, some weeks later, after the whole Sean debacle where he kidnapped the baby and she moved to being ffed, Roxy came out with this weird tirade whilst walking across the square, completely unprompted, about how she'd hated bf, how all the middle class yummy mummies made her feel dreadful for not bfing, etc. Because Roxy goes to mother and baby groups All The Time, doesn't she?! Again, a scriptwriter working through some issues...
Breastfeeding promotion is a public health issue. Babies who are bfed are healthier than had they been ffed. It would be nice if that weren't true, perhaps, for those who can't bf, or who weren't supported well enough to bf - but short of rewriting biology, it won't ever be true that ff is better for the health of the vast majority of babies (and their mothers).
Soap operas step up when there are other issues - they've done e.g. a domestic violence campaign - EastEnders, Casualty, etc all involved. And they've done some other v sensitive storylines around public health issues - e.g. AIDS. But bf is up there for ridicule - it was dippy Honey who bf, not capable (yet actually close on insane - burying Max fgs?!) Tanya.
It does seem as though they consult experts for everything else with this sort of storyline, yet they just go "Ah, I had a shit time, I'll have a rant about yummy mummies" re bf. Weird. And lazy.
If I was in charge, things would be different
