Who plays son in How I Met Your Mother?

The son in "How I Met Your Mother" is not played by a single actor.

The role of the son, who is future Ted Mosby telling his children the story of how he met their mother, is played by:

* David Henrie (as a teenager in flashbacks)

* Ryder Allen (as a younger child in flashbacks)

* Bob Saget (as the adult voiceover)

While we never see the son as an adult, Bob Saget's voice is what brings the story of Ted's life to life for his children.
