[lily's mom]

While I was at the store and my husband was incharge something happened to Lily's leg. I can't get a straight answer But I think she (my daughter) may be stepped on her leg. My daughter is three and is a lightweight. Lily will not walk on it at all. She doesn't make a sound when I feel it, however, she won't even put weight on it when she is laying down and trying to move. I don't think it is broke but should I rush her to the vet. We don't have any kind of animal hospital with an ER.
