It's never an easy call to make for sure, and God knows I've had plenty of experience with that.
My oldest just passed 14 1/2 years, and so far she's happy to toddle around the house, even gets happy enough she does a stiff-legged run/bounce thing.
She's also started wiping her face with glee on the sofa corner after eating, but hey at that age she can wipe her face wherever she wants!
I just cherish each day that God grants to me with her, you know?
