Can you imagine having twins?

I don’t think many people can truly understand what it’s like to have two bundles of joy, but Neil Patrick Harris says his kids are a blessing for him and David Burtka.

Harris, father to 15 month-old Gideon and Harper told Parade:

“I love watching them learn to understand language. And watching them interact with each other is fantastic.”

Having each other also gives his kids a natural companion to explore the world with, Harris said.

“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.”

On his days off, Harris reveals that he:

“Sleep! Nap! And I’m sort of a tool-around-the-garage guy. I’ve got a workbench and I like to fix things. Well, I like to say I’m going to fix things and then put them on my workbench and then never get to them!”

One indulgence is Twitter, which Harris says has brought him closer to his friends.

“It allows a kind of intimacy with people who want to follow you. You can toss them a funny joke or picture or story that’s unique to you and doesn’t come through the publicists and the studios. It’s just straight out of my brain, into my finger, onto my phone, and off to Twitter!”
