John Stamos reveals why he won't have another baby with wife Caitlin McHugh

John Stamos revealed the reason behind his decision to scrap plans to have another baby with his Caitlin McHugh Stamos.

Speaking to People, the 60-year-old actor admitted that the couple did have plans to expand their family after welcoming son Billy, now-five, however, “it just doesn’t seem like it’s in the cards,” he said.

"By the way, [Billy's] asked for a kid all the time, like a brother or sister. If we take three minutes of not paying attention to him, he goes crazy," the Full House alum continued.

"He could never deal with a sibling. No, I know he couldn't. He'd like it at first. Oh, there's a little baby, then me. We got to deal with a kid,” Stamos added.

Stamos gave a glimpse into Billy’s Spider-Man/Pokémon/Sonic the Hedgehog-themed birthday party on Instagram earlier this year, which he paired with a heartwarming caption.

“There is a conceit in corny romcoms where the protagonist says, 'You complete me.' As a Disney guy, I'm down with a certain level of sentimentalism and sappiness, but I never really understood the idea of being 'completed.' I get it now," the actor wrote at the time.

The Big Shot star gushed, "I still have a lot to do, but if my whole life was one sentence, then Billy would be the exclamation mark at the end of it.”
