Kids these days. They grow up so fast! It seems like just a few seasons ago that Teen Mom 2's Kailyn Lowry was pushing her son, Isaac, out of her lady parts during MTV's 16 and Pregnant, and now this little dude is 4-years-old and ready for school! Well, preschool that is.

Isaac has been home with his momma for years now (with the occasional stint in daycare, naturally), but it looks like he's about to start going to school full-time. Kailyn and Isaac just moved into a new home in Dover (where Kailyn's hubby, Javi Marroquin, works at the local Air Force base), and she's already getting familiar with her new nabe. Yep, she even found Isaac a great school!

"Just registered Isaac for the perfect little preschool!" Kailyn tweeted on October 7.

We're sure Kailyn will miss having her kiddo at home, but let's not forget that this gal is pregnant with her second child, and due to pop in just a few weeks! She's going to have her hands full taking care of the new baby, so it makes sense that she's putting Isaac in class. After all, it would be pretty challenging for Kailyn to balance two kids while Javi's off protecting the USofA.

Sigh, can you believe that Isaac's already in school? Next stop kindergarten, then elementary school, and before we know it this dude will be graduating college with a degree in Scentsy!
