Every now and then when Kelsey is walking she'll lift her back left leg up like it hurts her. She doesnt moan or cry or anything like that...but it just looks like it bothers her. The weird thing is that it only happens every now and then. I dont think it's broken bones, but I can't figure out what it might be?

I'm planning on taking her to the vet soon...but i have a feeling they wont be able to tell me anything differnt from what I already know.

Does anybody elses' babies do this...or have an idea of what it might mean?
