Since you already have a boy and your heart was originally set on a girl, i would wait and hold out for the girl.  Otherwise, you will be looking for number 3 before you know it!!  I had Oliver and then got Brooklyn and they hit it off right from the get go!!  Good luck on your choice!! Trust me, i understand the baby need!  Hence....my Benjamin...(new baby maltese!)  Just couldnt resist that adorable face!!
