Help trying to remember a film please?

It's not a recent film and I remember watching it awhile ago. It's
about a kidnap. A boy was taken when he was young and brought back
when he's a tiny bit older. I remember a certain scene where the boy
jumps on a bed, like young children do, but he won't make a sound and
he keeps his mouth closed because of what the kidnapper has done. I
can't remember the title. Help please
