Tickles?

Pretty much since her birth, Zane and I have been tickling Miranda. Or maybe I should say we've been trying to tickle her. For most of her 6 months of life, she has not responded to our little tickles. This was probably a good move on her part because we did not tickle very often. Just recently, she has been responding. The problem is that we are not sure if she is laughing or crying. So, here's a video of some of her tickles. What do you think? Does she like to be tickled or not? Let us know!
