Who played the little boy?
One of the nannies, the blonde one had a baby and the baby in her charge died, his older brother said for him to swap it for hers and at least it would have a good up bringing.
Who was the boy?
Are you asking about Hannah's young charge, Bertie? The character was played by this actor http://www.imdb.com/name/nm0370876/, Adam Hayes.
shareI wish I could find more information on Laurence Owen, who played Tom, the boy who shot his father and was sent away. Adorable child. He stole my heart.
shareThis user: http://www.imdb.com/user/ur7321621/boards/profile/ says the boy who played Tom is her son.
shareLaurence Owen segued into music becoming a composer. If you Google him, adding "actor" will lead you to the composer.
shareCome and see him tonight!
