So.. how old are you?

Ok, I know that every mum will brag about their child being the most beautiful, the most clever, creative, innovative, etc, etc. But honestly, she just is!!
Being a three year old and having a conversation like an adult is a day-to-day routine for Nicole.
Christmas is coming and she received a lot of Christmas cards from her friends in the nursery. One card was signed, Archie.
She said, "Oh, Archie is my best friend.."
??
As far as I know her best friend is always Sophie.
So in an engaging tone I asked her some questions (as usual!!), " Is he a nice boy, Nicole?"
"Yes, he is"
"Do you play with him a lot?"
"Yes, I do"
Then, searching my brain for more appropriate questions and vocabulary for her age, I asked, "Is he bigger or smaller than you?"
What I did not expect was her answer, "He is the same height as me, mummy"
'The same height??' Not 'He is as tall as me' or 'bigger or smaller than me'
Well done, baby... excellent use of comparisons.
Other expressions that she uses now:
"Hmm,... I wonder what's inside this box.."
Or
"I wish I could be as tall as you, mummy"
Or
I would ask her something like, "Do you think it is going to be a sunny day today, Nicole?"
And she would answer, "Mmm, I think so...."
So... how old are you again, Nicole? I feel like talking to an adult sometimes, bless you...
