I use their nursing pads (and the Udder Cover nursing shawl too) and haven't had any problems fitting them into my nursing bras or my regular full-coverage bras. My days of wearing demi bras ended when I got preggo with number one and went from a B to a C cup, but would be laughable after number 2 left me at a D. Nursing pads need to cover a lot more than just the nipple to absorb all the leaks. Lansinoh's washable pads are smaller and so are Gerber's disposable pads, but most are the size of the ones sold by Udder Covers. I have found them to soak through more often, so I double up if I wake up really engorged. Good luck!
