Was she really ever this tiny?

I'm going through Sasha's baby clothes right now (and giving them to a friend's brother who's expecting a little girl soon) and found this little white dress she wore when she was 3 months old. Naturally, she wanted to try it on.
OMG, how is this possible?! How did my little baby girl get so big and grown-up??

I'm so looking forward to having another little baby to cuddle and hug and squeeze and love on!
