Yes babies have a great understanding of body language and facial expression long before they can talk to communicate.

I knew it!

My wife is a social worker and she said the opposite and we had like a big quarel over it. I was 99% sure I was right, but I since she’s a social worker, she’s more the authority on this matter than I am (I’m an engineer) and I thought I’d double check, just to be sure.

Now I’m gonna rub this in her face 😁.
