I think she'll be a good Nana.

"Mrs. Darling loved to have everything just so, and Mr. Darling had a passion for being exactly like his neighbors; so, of course, they had a nurse. As they were poor, owing to the amount of milk the children drank, this nurse was a prim Newfoundland dog, called Nana who had belonged to no one in particular until the Darlings engaged her. She had always thought children important, however, and the Darlings had become acquainted with her in Kensington Gardens, where she spent most of her spare time peeping into perambulators...

She proved to be quite a treasure of a nurse.

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.

No nursery could possibly have been conducted more correctly, and Mr. Darling knew it, yet he sometimes wondered uneasily whether the neighbors talked."
