Just started thinking about this after reading the "BFing essentials" thread. How many of you regard a nursing bra as essential?
When I was PG I just assumed that I would need some nursing bras for BFing and bought a few which I used for the first few weeks.
My mum then commented on the fact that she had never used a special bra to breastfeed so I tried just using an ordinary bra and slipping the strap down on one side.
I found that this worked just as well for me (and was just as easy to accomplish with one hand under a scarf when travelling by train...) as hooking and unhooking the cup on a nursing bra.
Since then, I've been mainly back in ordinary bras which are generally cheaper, nicer and more likely to have underwiring (good when you're DD+ cup size).
