When we all adopted Barack Obama's family as our own in 2008, part of the agreement was understanding that no matter the actual pace, it'd always seem like his two children, Malia and Sasha Obama, were growing up far too quickly. 

So brace yourselves when we say the youngest Obama daughter, who celebrates her birthday on June 10, is now 20 years old. 

When we first saw Sasha, we're pretty sure she hadn't even reached the 3-foot mark. Now, she's studying at University of Michigan, sings the City Girls like the rest of us and casually chills with Cardi B and Offset. 

We're absolutely all getting old. But what better remedy for aging than a trip down memory lane. 

Here are some photos of Sasha Obama throughout the years.
