I'm going in Tuesday, so I'm putting my guess in now under the buzzer. I personally keep going back and forth. This pregnancy is so different from DS's, so I've thought girl. But when I was 16 a palm reader told me I would have 3 boys, so maybe boy. DH's side of the family all think boy. When I asked my little precog 2 yo niece what the baby was, she said girl. Her little brother was supposed to be a girl according to their anatomy scan, but during her mama's labor, my niece started saying, "Mama's baby is a boy." So maybe she's on to something with her unborn cousin. I would love to have a boy and a girl, but I can't even wrap my head around a girl for some reason, so I'm thinking maybe boy.
Well, I'm going to put myself down for girl based on the fact that I've been stressing about girl names.
All will hopefully be revealed Tuesday.
