I'd suggest that if Himi has begun to stabilize in terms of growth, that could be a good thing. Any more growth much beyond this, we're getting into the "difficult to simply get around" size - and I'd be saddened to see her get to the point of seriously needing to consider reduction.
Anyway - sounds like the pills were for her sister. I wouldn't mind seeing her sister start to catch up, size-wise.
