This was recommended to me by a mother in my online chat group. I bought one when I was 7 months pregnant and after my daughter was born I used it all the time! I actually went and bought 2 more cause there were times when one was in the wash but she wouldn't sleep without this. The only problem is that it only comes in one size and my daughter who was 9.5 lbs and 22 inches long at birth quickly grew too long for this, but she also stopped wanted to be swaddled so I guess its not a big deal she got too big. Swaddling is great for newborns cause they jerk their arms and legs and it freaks them out and wakes them up.
