I first noticed this a fwe weeks ago when she came up the stairs and I was in my bedroom, every step I heard her knees click. I have observed her since and most times if she kneels down, stands up, goes up the stairs her knees click.
Has anyone ever noticed it happening to their DC, do I need to worry or is it just a phase she is going through?
She does 3 different types of dance a week, but nothing really strenuious!
