phdlife Sure, a badly fitting underwired nursing bra can have pressure points and lead to blocked ducts. So getting a good fit, especially round the sides to the arm pits is important.
I've been exclusively bfeeding for 6-1/2 months with no problems at all wearing this bra.
I plan to breastfeed for a good while longer and it's important to me to feel comfortable, supported and for me to look ok under clothes -- I'm a 32F now and non underwired bras (I tried a good range) felt uncomfortable and created mono-tit. Feeling good about myself, and normal in clothes is part of feeling able to continue with breastfeeding in the long term. Like having a few glasses of wine or something.
The wire doesn't dig in, just supports the bigger bust, the clip is easy, the bras have kept their shape in 7 months of washing.
I honestly can't see what the fuss is about if you get a decent fit. Now breastfeeding is well established I also wear normal underwired bras (like a wonderbra even) and I find whopping the tip over the top keeps the nipple at a good angle and height for feeding out and about.
Oh, for the larger chested, those Mothercare vest tops are rubbish. Awful. Emma Jane ones just about cope with my massive tits. I recommend them, although they look a bit weird.
About 3 months in you'll probably just be wearing normal clothes. And ahem some maternity clothes
