Maddy's tummy

So last weekend, Maddy had an upset belly. On Sunday, at Reagan's birthday party, she got bopped in the nose. She bled like a stuck pig - all over the place. Once she calmed down, she was fine. On Wednesday night, she had a bloody back end - we didn't know what to think. So we took her to the doctor. I never thought it could have been the accident on Sunday. So now she's got an upset belly again. I wonder what it is this time. Ugh.
