Allison Williams' son has a lot to say!

While appearing on Thursday's episode of Late Night with Seth Meyers, the M3GAN actress, 35, chatted with host Seth Meyers, 49, about her 2-year-old son Arlo, reflecting on how much he's grown in the last few years.

"A lot's changed since the last time . . . Arlo! You have a baby, who is turning 2 in November. How is it?" Meyers asked Williams.

"It is so wild. He's like a full — when I watch baby videos of him now, it feels like I'm watching him trapped in a body that didn't perform in the way that he needed," Williams joked.

"I watch him make the sounds newborns make and I'm like, 'Oh my God, he was trying to tell us so much.' And we didn't know! We just thought he was . . . you know, had a dirty diaper or something, but he was trying to ask very complex questions."

"Yes. It is funny how you can . . . you can't think . . . you can look backwards," Meyers said. "You can see him now and you can't project forward. But you can go, 'Oh yeah, you were gonna be this the whole time.' "

"Yeah, and he is just consistently that guy," Williams responded.

Williams shares her son with fiancé Alexander Dreymon, 40.

Earlier this week, the actress appeared on Wednesday's episode of Live with Kelly & Mark, telling hosts Kelly Ripa and Mark Consuelos that her dad, Brian Williams, had been bragging about his grandparent skills.

After Consuelos asked if her dad was a diaper changer for her son, Williams said that he's "going to be offended" by the question since he thinks he's the "world's fastest diaper changer."

"He brags he can change even a poop diaper in under 60 seconds. He is like a pit crew. He has like . . . it’s really fast. He comes in, baby’s down, he’s got — there’s some kind of Aquaphor with the new diaper strategy he has," Williams said.

"It is so impressive. And he and Alexander raced once, and I don’t want to embarrass either of them but it was very close. There might have been cheating. It was like, a big deal," she revealed.
