is this a scrotum or a girly bit - 13 week potty shot?

13 weeks is too early for a potty shot but I wouldn't rule out hearing girl xx

I think the legs are too close together regardless... My current little man looked like that at 15 weeks and he's a boy

I wouldnt say boy for sure at all. I think you are still hanging at 50-50. I can't see a nub on the side shot :(. But hope its your girly baking in there!
