Isn't that funny

Dear Jack,

These days, you are so funny. It's like we're watching more and more of your personality emerge every day. I've always thought it was amazing that one of the early things a baby develops is a sense of humour. How great is that?Well, sense of humour you've got. Even at nine months, you know when you're being funny (and have for some time) and you love to make people laugh. Here are some of your favourites these days:

Running man: if we hold you up and away from our bodies, you kick your little legs like you're running. You've also just added shaking your head back and forth while you run. You laugh the whole time. You've also started doing it anytime you want to show you're excited to see someone.

Mmmmmmmmmm: you love food. All food. But when something is especially good (or when we ask you if something is good), you say "mmmmmmmm" with your voice bouncing like a little goat. Everyone always laughs when they hear it. This makes you do it more.

Blowing raspberries: if anyone makes a sound even sort of like a raspberry, you make one too. Except yours are really spit-y.

Gasping: these days, you like to be the centre of attention (at least when you're with people you know). When you notice people are paying attention to something that isn't you, you make a sound sort of like a gasp and laugh combined. If people look at you (or better, laugh) you do it again and again.

I could add more and more to the list; there are new ones every day. You can be frustrating at times, but man, are you funny.
