This is pretty interesting! According to this theory, a girl will have a more rounded forehead and a boy will have more of a slope forehead. This is my sonogram at 14 weeks. And the skull looks to be more sloped straight down then rounded and bulb like... but it's still too early to tell. What do you ladies think? And has anyone else ever looked into it?

when pregnant with my other kids, and have said "the profile just looks like a ___(insert boy/girl here____!" So this theory excites me and could definitely be plausible. I should dig out the albums and look to see if it holds true to my kids.
