Nanny McPhee: The Five Lessons

You all know that there is seven children, but what about the first?
Simon,
Tora,
Lily,
Eric,
Sebastian,
Christiana,
And Agatha.
But they had an older sister.
Her name is Emmalyn.
She is loved dearly by her younger siblings. But.... To save Chrissy, Emmalyn goes with her Great Aunt Adelaide, to the Stitch Manor to learn. Along with Evangeline.

When she comes back, everyone is surprised. Simon cares most, as Emmalyn is the most caring sister, a motherly figure. She sings Loolaby to them.
Emmalyn always went along with their plans, although she highly disapproved of it.

She missed her siblings, and vice versa. She is a 16 year old girl.

And she is very glad that Evangeline is her new mother.
