Celebrity Parents of Twins Talk About Their Kids

The How I Met Your Mother star and his partner, David Burtka, are dads to 2-year-old twins Gideon and Harper.

In an interview this past January, NPH told Parade: "Watching them interact with each other is fantastic. We're lucky that we have two because they always have a playmate and they get to learn complicated concepts, like sharing and cooperation. They get to learn those things a little earlier because they're with each other all the time. Watching their minds tick is fun."
