Sofia Richie was charmed by Scott Disick’s children in their first public appearance together, but a sources says it’s given her second thoughts about their relationship.

“I’m too young to mother his kids,” she reportedly said.

Richie, daughter of music legend Lionel Richie, is only 19 years old. She’s not even old enough to drink alcohol or step into a club.

And, she’s not about to miss out on her youth by being tied down to a family that’s not hers.

She’d virtually be a babysitter with benefits.

Scott is 34, and 15 years her senior. He’s currently living apart from his baby mama Kourtney Kardashian. They were never married despite their long-term relationship.

They had three kids together, Mason Dash Disick, 8, Penelope Scotland Disick, 5, and Reign Aston Disick, 3.

In fact, Sofia is closer in age to Mason.

Kourtney’s half-sister, Kendall Jenner poked fun of the fact. “Awww Scott and his kids,” she commented on a social media photo, shading their age difference.

Sofia met with Scott and the kids at Nobu in Malibu, Friday (Jan. 26) for about two hours.

Sofia didn’t even sit with them. The kids, sans Reign, were at a separate table.

Sofia reportedly “seemed comfortable with Scott’s kids,” E! News reported. But they were very obviously uncomfortable with her.

“They all stayed close to Scott,” insider told People.

“It was a short dinner. Scott and Sofia were not affectionate. The kids seemed fine with her, but all sat close to Scott. He helped them at dinner and with potty breaks.”

There were also signs the relationship is cooling. “Sofia acted like Scott’s friend,” the source added.

Sofia is facing a lot of headwind in her relationship. Her father thinks the worst of Scott and his “playboy” ways.

“He thinks Scott is the worst person she could ever see and that he raised her better than that,” says another source.

Kim Kardashian has also openly criticized them.

Our source says meeting the kids was a wake up call for Sofia. While she’s fond of Scott, she just can’t see herself being tied down caring for his kids.

“She knows if the relationship gets serious Scott will push them off on her, while he goes gallivanting around Hollywood.

Who needs that when you’re 19?
