Not sure if this has been covered in other posts but wanted to pass on my new find. The thought of sleeping in a bra was filling me with dread as they're so uncomfortable. I had been sticking breast pads to the inside of a vest top but as you can imagine things move around when you lie down (!!) so not the ideal solution.
I found the Carriwell bras from the Nursing Bra Shop which are seamless and really comfortable to sleep in. The whole cup drops down exposing the whole breast which the little one likes.
Looking forward to trying their other breastfeeding bras as they seem to be less expensive than John Lewis etc... and more attractive.
