Solicitous means showing anxious care for somebody's wellbeing. Solicitous of her health, solicitous attention, overly solicitous.
The anxiety in it is what separates it from kind, and too much of it becomes fussing. It nearly always takes of or about, and it is a formal word that suits waiters and doctors in fiction.
