Some of the things you have been saying recently

Before I forget to get a record of these things and they get lost (or worse still, mis-remembered) I wanted to get them down.

Willn't

This is fascinating to me. It is very clear proof of your understanding of language because you are not only parroting words, sentences and phrases you have heard before, but you are applying grammatical rules on your own. You are aware of how to make a contraction of, say, "Do not," because you simply turn it into, "Don't." 

However, you are applying the same rule to the more irregular contraction for 'Will not' - 'Won't.'

Applying the same rule, it comes out, "Willn't." 

This makes your mummy and daddy both smile, particularly because you simply will not be persuaded otherwise. 

Talking about not being persuaded, you are now at your most independent. At every given opportunity you want to show that you can do whatever it is mummy and I are doing. Even something as simple as passing you your drink gets you all argumentative. You put it back on the table and say, "I wanted to get it!" or something equally charming, lovely and polite. It's truly a delight.

You keep saying brilliant things too, don't get me wrong.

This morning, your mummy passed you a car and said, "That's a good car isn't it?" to which you replied (honestly, truthfully),

"Yeah, stupendous."

Your mummy and daddy looked at each other, smiled and got you to repeat what you had just said because we wanted to be sure. 

You said it again.

You've also taken to saying, "Sorry I'm late," when you go to get a book in the evening.

Oh, and you now say, "Of course you can," if we ask you if we can do something.

These may not sound like particularly good things but you somehow seem too young to say such things as naturally as you do.
