Chris Pratt‘s son Jack is learning a lot of new words, but there’s one that stands out for the actor: “Dada.”
“I do have video of him saying ‘dada’ when I come on the screen,” the Parks and Recreation actor, 34, told PEOPLE at the show’s PaleyFest panel on Tuesday. “He knows a lot of words, colors, numbers. He’s very advanced for his age.”
Continued Pratt, unable to resist a good joke: “He also can type 90 words a minute, which is really good for an 18-month-old!”
After spending five months in London last year to film Guardians of the Galaxy, Pratt had worried that Jack, his son with wife Anna Faris, wouldn’t remember him.
“He recognized me when I came home,” Pratt told PEOPLE in October. “I was worried that he wasn’t going to recognize me, but he recognized me from Skype.”
