Is there an echo in here?

Funy little girl...always makes me laugh.

So Stella has had this little dry cough for a couple weeks now.  No other symptoms, but it was starting to worry me nonetheless.  My mother in law was over the other day and said she thought Stella just liked the way it sounded when she coughed.  I was thinking "No way...Babies don't do stuff like that....do they?". So we were playing last night and I decided to do a little fake cough just to see what her reaction would be.  Well she laughed and laughed like it was the funniest thing in the world.  (I wish I'd taken a video....we'd be youtube stars right along with that other laughing baby that everyone is so crazy over.) So I figured, she really must like the way it sounds.  So I did it a few more times and she kept on laughing and then....something magical happened.  She started mimicking me.  I'd fake cough, then she'd giggle and fake cough too. And now it goes both ways--she does the fake cough and I do it back, I do the fake cough and then she does it.  Hilarious.  My baby is a little comedienne.  Ah well....you can tell I don't get out much these days.
