Henry totally copied Patty today. He was on a blanket on the floor near us while we sipped iced tea and chatted, like we do, and every so often Patty held her hand out to him. You could see him concentrating on her hand and when he looked away, she stopped doing it. When she'd do it again, you could see his arm twitching a little like he wanted to reach out to her. Then she started opening and closing her hand right above him and his little hand twitched, trying to open and close!!
It is amazing to watch him learn and try. You can see his mind working.
