Why does everyone keep telling me that I “need” a girl? Am I not allowed to be happy with my two boys? I’ve had a c-section and got my VBAC. I’m not sure I want to go through that again not do I really want three children. A friend of mine and my mom already have an outfit for my “future daughter.” I just gave birth 2 weeks ago. I mean, really?
