You Decide
Esme has always known.
There has never been a day when she did not, because you do not reveal a thing like this, you simply never conceal it, and I had that advice from two professionals and from Imogen Achara and it is unanimous.
What she has, at four, is this: she lives with Tía and Papo.
Mamá lives in a different house and comes on Saturdays.
When she was a very little baby she got hurt and her leg was broken and she had to wear a special brace, and it is all better now.
