It was a great moment forthe Busbys, and Olivia’s laugh just made it all the more memorable.

“She is goofy like Ava but in a different way.

In fact, Olivia shares a special bond with just about every member of her family.

However, she is most dependent on her identical twin, Ava.

It was probably hard for Olivia to be in a class without her twin, at least at first.

After all, they’d always been together.

Still, Adam and Danielle knew it would benefit both girls to foster some independence.

And when they get to Olivia, it’s clear they were already exhausted.

“Olivia is a hundred percent the entertainer, comedian in the house,” Danielle told the cameras.

To prove her point, the promo cuts to a clip in which all the quints are painting together.

The ongoing battle between Olivia and Riley is so well-known that there was even aTLC cliphighlighting their rivalry.

“Those two have always bickered more than anyone else,” she continued.

“They just don’t mesh well,” Adam added.

She loves to laugh, and everything is funny to Olivia,” Danielle detailed.

As Olivia has grown, she’s retained her laid-back attitude.

That doesn’t mean she isn’t a freethinker, though, as her mom pointed out.

“However,” Danielle clarified, “she is super opinionated.”

Riley sees Olivia not wanting a floaty, and so she doesn’t want to wear a floaty."

While some kids love trying new things, others are comfortable with the status quo.

Of the Busby quints, Olivia was the one all about trying new things.

“The twins, Ava and Olivia, are just super sensitive towards their tantrums.

It’s dramatic screams,” Danielle explained, seemingly exasperated at Olivia’s terrible twos behavior.

And that sensitivity wasn’t exactly anything new for Olivia.

However, Olivia Busby also encountered health problems as a baby.

However, her eyes weren’t the only concern.
