I'm 26 - I'm a Feb. baby too, so unless this babe decides to appear 5 days early (unlikely), I'll be 27 when s/he arrives. DH will be 28.
I was due ON my birthday (2/11) with DD and she arrived on 2/19. This time I'm due 2/16, so I guess it's possible somebody will share a birthday! Fine by me, we'll be sharing parties! February's a busy month for us, we have 5 other family bdays in Feb!
