Hallie laughing

Hallie has been laughing for sometime but I have yet to get her to do it long enough for me to get it on video. Lately when she gets excited she pants and squeals. A couple days ago I was getting ready and she started getting excited about something so I started to pant and squeal back and she really liked it. Dont pay any attention to the wierd noises I was making. What you do to make your kids laugh.
