What does it mean?

I've become aware recently that Tabitha is wanting to walk less and less. She is demanding to be carried more, and is taking longer to get anywhere. I've also noticed a deterioration in her gait, she has more of a pronounced limp. I don't know what is causing this, whether its the leg length discrepancy increasing, or if her exostoses are beginning to impact on her mobility, or if she is in pain.

Once again, I wish she could talk....
