My favourite moment was in March, my daughter was about to turn 2 and wasn't speaking yet.
I asked her if she would like to hear some music.
She made the sign for dog.
I searched youtube for some songs about dogs and she shook her head.
She made the sign for tree.
I was like "dog, tree", she nodded. Hmmm...
I was searching for "dog tree music" when one of the pictures that came up was a christmas tree.
She pointed to that excitedly!
I was like "dog christmas tree music" ... it took me a second to realise that she wanted to listen to the Charlie Brown Christmas soundtrack that I had had playing off YouTube at Christmas 3 months previously!
I put that on again and we danced around to it.
I thought that was totally wild! It was the first time I remember her communicating a really sophisticated preference other than just wanting to eat/drink/help etc.
