I felt strongly at 6 weeks preggo with DS1 that he was a boy, with DS2, I wished with all my might that the baby inside was a girl.....and I can't say that I feel one way or the other this time around.
I firmly believe that you longtime or skinnymini or surprise mamas will have little girls in the Christmas season. If I am forced to guess a gender for myself, I will protect my emotions and say little boy.
As for lucky.....my DS1 has oodles of it...maybe that is one reason I should hope that I am preggo with his sister! I know that I am blessed with my little guys and for the next while, choose to let go of the fear that I will never have a daughter.
