She proved to be quite a treasure of a nurse.

How thorough she was at bath-time, and up at any moment of the night if one of her charges made the slightest cry.

Of course her kennel was in the nursery.
She had a genius for knowing when a cough is a thing to have no patience with and when it needs stocking around your throat.

She believed to her last day in old-fashioned remedies like rhubarb leaf, and made sounds of contempt over all this new-fangled talk about germs, and so on.

It was a lesson in propriety to see her escorting the children to school, walking sedately by their side when they were well behaved, and butting them back into line if they strayed.
