DH and I have just had DC3 and I'm surprised at the amount of people who think it's a lot. (Not that it doesn't feel like a lot some days :o)
We've gotten so many comments about having our hands full, "surely you're done now", " wow! Three?!", etc. DH was a party the other day and the host introduced him to someone else and said "he and his wife have thirty seven kids or something."
Obviously he was joking, but most people seem the think that three is a lot.
I thought 4+ was a "larger family", personally. Am I mistaken?
