I was wondering if it's just my daughter that does this or if its normal for her to be doing this now. Last week we noticed that while we were talking the baby would start shaking her head as if to say "no".

For example: I was talking to my mom and I was saying how the baby's diaper almost destroyed my nose hairs because of the smell. As soon as I said that, she started slowly shaking her head. When I said "No? It didn't burn my nose hairs?" She started smiling and did it again.

We're pretty sure that she hasn't fullly grasped the meaning of no yet, but we find it hilarious and perfectly timed.
