Sharing scenes from the family park outing on her Instagram Story Wednesday, the former radio personality, 32, showed just how much twinsZion and Zillion, 19 months, have grown.
The first video De La Rosa shared shows the two boys playing with a giant abacus in the park, crouched down together before turning around and looking at the camera and toddling off in different directions. Both were dressed in cranberry red pants, gray sweatshirts with a raccoon printed on each, and checkered slip-on Vans sneakers.
In another video, the proud mom shows Zion playing in the same area where he took his first steps.
“Zion took his first steps at this very spot,” she recalled. “He wanted to ring the bell then and now. Time flies.”
