last week, on her 4 month birthday, sylvie learned how to mimic us. i blew a raspberry at and her and she blew it back. at first i thought it was a fluke, so i did it again. to my surprise, she blew one back! we went back and forth this way for a good 20 minutes. she's done it again everyday since. i finally managed to catch it on video over the weekend.
