I know it's kind of strange that my current favorite expression of yours is "No papa."
The way you say it is so cute and innocent. "Do you want some agua?" "No papa." "Time to get dressed." "No papa." "Do you want to snuggle with papa?" "No papa."
Every once in awhile there is a "Yes papa." I like that too. But the "No papa" shows me that you know what you want and that you won't settle for less." I like that about you.

And you of course understand everything -- many things in three languages!

You want to do everything Max is doing, which he usually allows. When he does shut you out, you don't pout you find something else to entertain you. And frequently whatever it is you find, you're brother is soon wanting to join in. The two of you are so darn close and so loving to one another.
You're growing up. You're learning things every day. And your skills in every way are getting better. Soon you'll be talking in complete sentences. I'll miss the simple expressions like "No papa."
