Toddler Scolding Twin Brother Like She's His Mom Is Cracking People Up

Just because twins are usually super alike doesn't mean they can't be significantly different from each other, too. Whether they're identical or fraternal, twins have distinct personalities that sometimes even clash...but can also complement each other in surprising ways, too.

In a video posted on June 4, a toddler girl proves that she's the "responsible" twin when her brother starts being mischievous — and she probably saves her mom a whole lot of cash on a new TV in the process! This kid isn't about to let her bro break the rules, no matter how many times he tries to step out of line.

"Trying to keep bubba out of trouble! It's so cool to see her pick up on and enforce rules we make in this house," wrote @candacenysm . She was remarkably patient about the whole thing, too — even if she did seem a bit fed up by the end, as commenters pointed out!

"It's the thank you at the end, it's the kind of thank you I give my kids when I've had enough of telling them the same thing," wrote Kellymarie.

"She's all 'let me have that one too, just in case,'" wrote emilynelson485.

"Oh too funny!! She's being the best lil mamma!" wrote Marye Brown Hash.

Seems like a safe bet that the dynamic these two have now will probably continue as they get older ! Experts say it's normal for one twin to take more of a leadership position.

What Makes One Twin More Dominant?

According to Discover, "research suggests twins’ personalities may develop , in part, based on who is larger and healthier at birth. As it happens, the firstborn twin usually snags those defining characteristics."

“'Twins unconsciously negotiate their relationship so one person in the pair is the designated leader in certain aspects of their lives,' says Caroline Tancredy, assistant professor of psychology at the University of Illinois. While hard scientific research in this arena is scant, existing evidence suggests gender, size and weight may play large roles in which twin rules the roost."

Interestingly enough, there is a caveat — which is that girls often take the lead in boy-girl pairs, "regardless of their size or birth order."

It's not completely clear why this is the case , though prenatal hormone exposure could have something to do with it. Whatever the reason, the twins in this video are proof that it happens!
