Today my daughter and I communicated about something specific. This wasn't noise for noise sake. This wasn't a general outburst that I then had to decipher and guess about, it was a direct instruction.
I was helping her have a drink as we approached the end of breakfast. Although I was holding the cup near her, I decided to wait a few more chews before offering it to her. She made a distinct squawk that meant "drink now." I was so happy to understand what she wanted I was more that willing to oblige. She drank gratefully. What an incredible moment.
