Here in the UK, the most common opinion, regarding finding out the sex of a baby, seems to be that people ought to keep it a surprise until the moment of delivery. I have even encountered people who flat out told me that they thought it was ridiculous that some people wanted to find out the sex before the baby was born.
When I tell people I do want to find out the sex at our 20-week scan (tomorrow!) they look at me in a slightly disapproving way and ask me why I don’t want to be surprised. But I do want to be surprised.
I just think, on the day the baby pops out, I will be pretty busy and there will be more than enough surprises already. I see no reason not to have one surprise 20 weeks earlier. I like to spread the fun a little.
And I will be surprised, tomorrow, when the sonographer tells us the sex of our baby, since I have no idea whether our little one will be a boy or a girl.
