How old?!

It appears my mind has frozen in time since having my second child....two years ago when I had Jamie (the boy) Flynn (the dog) was 9 years old...and up till today I've been telling folk, when asked, that he is 9 this year! What on earth! I've only just realised today that he is, infact, 11 this year! And that was only because a friend of mine who has a dog the same age told me and then i realised! What happened there?! Two years....gone.....poor Flynn! ( And does that mean that technically I'm only 40 this year?!)
I'm a BAD doggie mum!
