My twins are almost 4 months, and we still use my Brest friend! I was only able to nurse for a month, but still use it to ff when they need to eat at same time!
My twins are 7 months and we use the Brest friend pillow. I like it well enough. It doesn't quite tighten enough to be tight around my belly (there is a gap between the pillow and my stomach) but it doesn't really effect the nursing too much! Hope that made sense.
