I got a medium, and it's way too big for dd. so I got a small, and it's the same freakin' size as the medium. So I got a newborn, if it's too big I'm going to need to get the three of these freaking pieces of #$^ out of my house!
I just want something that FITS! And she's 13 mos old!
My DS wore the nb bumpy wool from about 6months (11lbs)to about 12 (17lbs) months. He is a skinny guy too!! But yes, it is huge for newborn. besides, it has a big rise, way too big for my 18 inch newborns.....
I know that they run a little bit big...I never used the size NB but I did start out using the size small at probably 2 or 3 weeks and he was a big baby. He was probably around 11-12 pounds when he started wearning them. He is now wearing a size large (at 6 months old and 21 pounds).
