Congratulations!

Hey I got the same and I am 33!!!!!
When they looked shocked just say - we want two more after this one and then we will stop.
I saw a family on the weekend with 6 kids - I noticed them because the mother yelled out loudly - yes there are 6 and we still haven't finished! Obviously she had yet anoher person comment on the size of her brood....

People are dumb, regardless of your age. I'm sorry your friends suck though.
