I am guessing that you are talking about a Mamma's Milk sling? I have one, and I LOVE it. Dd just grew out of the cradle hold, but she loves the heart to heart or hip hold in it. She just turned 7 months. I did have to buy two sizes since dh is really a much bigger size than I am. It is a bit of a pain to adjust, but I don't adjust it every time. I just put it on, slide her in, and away we go. DH still hasn't used his. Oh well! If dh and I were closer to the same size, then we could have easily used just one.
