I have a 4-month old daughter and received these as a gift and we love them!  we also have the Trumpette Pixie socks (white sock, with colored slipper, with bow).  I think I get more compliments on her socks than any of her outfits.  I just ordered these for a friend who just found out she's having a girl.  It may seem a bit pricey for socks, but they are really cute and make an excellent gift!  The sizing is a bit misleading.  My 4-month old is starting to grow out of these socks already, so I wouldn't count on them lasting 0-12 months as the size indicates.  I've heard the Trumpette socks for toddlers also run a bit small, so I'll likely order some of those soon for my 4-month old.
