That's an interesting view on it Lilac and can totally understand what your friend means.
Well we have another reassurance scan next Sunday and we were told they could probably tell the sex at that point. I'll be 16+3, so we'll need to decide before then. Hubby has now said he'll ask the technician to write it down and put it in an envelope, then he'll give the envelope to a baker and ask them to make the inside either blue or pink but not to tell us. Then we cut the cake with close family and all find out together. So I'm warming to that idea.
