Ha ha- the quiz gave me 50/50. Helpful.
I thought "girl" instinctively, but all my girlfriends are saying "That is a boy bump" so who knows. I've got one DS and can see the advantages of both another boy and a girl, so don't mind whichever.
I am 32 weeks now so only another 8 wks to wait. We found out for DS, but decided as this is definitely our last baby, we'd do things differently this time, just to mix it up a bit.
