Welcome pinga!!!!
Proudmama I am really hoping you get a girl. I can totally understand being grateful for your little boy, but at the same time still wanting a girl. It's definitely possible to feel two different emotions at the same time. My bestie's sister wanted a girl really bad. She already had a boy and when she found out her second child was a boy, she broke down crying at her scan. She convinced her hubby to try again for a third time on the condition she get her tubes tied afterward, and again it was a boy. She loves those boys to death, but I know that a part of her will always be yearning for that girl she never had.
Also my dh is the youngest of seven boys--the result of my MIL trying for that girl. She now as a ton of granddaughters though.
