slip of the tongue

It was 7.45 this morning and I was coffee-deprived when the following conversation took place while waiting for a meeting to start.
Junior Doctor: Hey, Illanare, I'm sorry I haven't got back to you about when I can commit to a week of teaching.  I wasn't sure what my availability would be (lowers voice) as my wife is pregnant.
Illanare: Oh, congratulations!
Junior Doctor: Thanks!  Yes, I didn't feel like I could commit to teaching until we had the 12-week scan.  That was last week and everything is fine, actually she's 13 weeks now. It feels like we had to wait forever for the 12 weeks to pass.
Illanare: (whose few functioning brain cells are only thinking about coffee) yes, the first trimester can feel like it goes on for twice as long.
Junior Doctor: Ah, so you have children!

I was back in the moment with a bang and had no idea what to say.  After what seemed an eternity, I mumbled "er no, I don't" and then thanked a god I no longer believe in for the meeting chair calling us all to order.

I was off my guard and so ended up blindsided.  What would you have said?

FB status - updated

You know all those "repost this if you are a mummy" status updates we see on In Yer Faceb00k? Well my cousin (mother of two living and one lost) posted this an hour ago.

This week we remember all babies born sleeping or who we have carried but never met and those we have held but could not take home. Make this your profile status if you or someone you know has suffered the loss of a precious baby. The majority won't do it, because unlike cancer, baby loss is still a taboo subject. Break the silence............... In memory of all our sleeping angels ♥ ♥

Updated: I hadn't re-posted this on my FB page - but I am just about to.
