I know it's never 100% but we were told that DC2 looked like a boy. I had another scan earlier due to minor complications and sonographer said looks like a girl eek! DD1 was freaked out at the idea of a sister so we were thrilled for her that it's a boy. Now, well, it's likely not given that this scan is at 29 weeks. I have another scan in two weeks so we'll try to get a better idea then. Nursery is painted light blue and we've been selling girls clothes - bah! Haven't sold too much so not a real problem but what a drag! DH and I are happy with a healthy child of either sex but oops.
