I had my 20 wk u/s and we told the sonographer we didn't want to find out the sex of the bub.

He then made reference to the baby being a 'he' and when we looked at him he said "I don't know the sex but often refer to the babies as being 'he's".

Has anyone had the sonographer slip up on the sex before? We are happy for either as long as the little one is healthy - but we really wanted it to be a surprise so now I think my hubby is really excited thinking it might be a little man....

Would be interested to see if this has happened to others and then you've actually delivered the opposite sex?
