How does Louisa (Louie) remember Henny from the time they first met in the novel, The Man Who Loved Children?

From the text:

"Henny, in the crowded perspectives of Louie's childish memory, had once been a beautiful, dark, thin young lady in a ruffled silk dressing down, mother of a very large red infant in ruffled bassinet, receiving in state a company of very beautiful young ladies, all in their best dresses."
