I got an A&A blanket this time around for the first time (this is baby #3). It is BY FAR my favorite piece of baby gear. I love, love, love it. It's so big that it's easy to get a tight swaddle (for me) by wrapping over and over. I have a hard time getting other blankets tight enough.
With my second son, I did use a waffle weave knit blanket from Babies R Us that I liked reaonably well, especially for like $7.
But, this A&A blanket is the best thing I ever purchased.
I should say, my babies are pretty large--14 lbs by 1 month old.
