I've heard great things about the GMDs. I also hear good things about Bummis NB covers, Thirsties XS, and Proraps. Seems from pictures that Bummis get the smallest and are best for even the tiniest chicken nb legs.
Happily married, WAHM of C (15), M (3), and E (1). Expecting a very big surprise baby on 3/25/14.
