Stealthy move...

Dear Nicky,

You're a sneaky fellow, all right. I went to the doc's in the city today for my cough, which he thinks is asthma/allergies/reflux by the way, and you guys were here with Granny and Mom. Well, apparently, at one point, you were on your tummy and the next thing you know, you're sitting upright, but the thing is no one saw you do it. Now don't get me wrong, we want you to figure out how to sit up from lying prone, and we're very excited that this might be something that could happen soon, so you keep practicing, in secret if you have to. You're brave and hardworking and despite all the work we make you do, you're still a good sport and sunny as the day is long.

Love,
Dad
