I used these when I was nursing my first child, and I loved it because it is very soft and comfortable for the night - and easy to use for nighttime feedings - no need to unbutton anything. I had my son in the summer, so I used to even just wear it during the day at home.
A soft and comforting sleeping bra...supports just enough for more comfortable sleeping at night. Great for when you want a relaxed bra on at home, too.
