In case anyone didn't see this on Matt's blog, here is Wil in his Hallowe'en costume:
Grandma Gussman made it for him. The pattern she got said it was "newborn" size. His feet sit approximately at the pelvic girdle. I didn't think my newborn was freakishly small, so I'm going to guess someone at the pattern company hadn't been around newborns in quite awhile.
