Alex Drummond can't believe how quickly Sofia is growing. 😭

In a sweet update shared on her Instagram Stories, Alex opened up about Sofia's growth, revealing just how far her little "peanut" has come. "She was born tiny at 6 lbs 3 oz and dropped to 5 lbs 6 oz right after birth," Alex explained. (That's completely normal, by the way!) "At her two-week appointment, she was in the 10th percentile in everything."

But now, Sofia is more than 13 pounds, landing in the 42nd percentile for weight and the 74th for height. "Makes me so happy to see those numbers climbing!" Alex wrote. "Maybe she'll be tall like mommy?"

Considering the Drummond family genes, a little extra height wouldn't come as a surprise! After all, her uncles Bryce and Todd tower over everyone, and Alex herself is considered tall—but even she looks short next to Paige. Ree is no stranger to making jokes about the challenges of family photos when you're surrounded by tall cowboys.

Alex shared that Sofia "just needed a little time to play catch-up," and clearly she has. Since welcoming her baby girl almost four months ago, Alex has kept followers in the loop with sweet updates and milestones—like Sofia's first rodeo, precious moments with her brother George, fun visits to Pawhuska, and her adorable new habit of watching Ree cook on Food Network. Sofia even experienced her first-ever weekend without her mom recently, spending a fun few days at home with Mauricio and her Abuela while Alex celebrated Paige's bachelorette.

Through all the little milestones, it's clear Sofia is thriving. We can't wait to see how much more she'll grow (though Alex might appreciate if it slowed down just a tiny bit).
