Fans ‘Can’t Believe’ How Fast Dylan Dreyer’s 3 Sons Have Grown Up in New Family Selfie

Fans were stunned to see new evidence showing just how much Dylan Dreyer’s sons have grown up as the mom of three marked the new school year with a collection of photos on social media.

A five-part Instagram carousel that the Today co-host shared on Friday, Sept. 6, kicked off with a photo showing all three boys posing together, flashing toothy smiles at the camera while wearing casual outfits of shorts and shirts for the school day ahead.

Dreyer’s oldest, Calvin , stood more than a head taller than his younger brother, Oliver , 4, as both wore backpacks. Rusty , Dreyer’s youngest son who turns 3 later this month, smiled shyly at the camera as he posed solo in a subsequent photo.

Dreyer’s Instagram post also included solo snapshots of her two older sons, as well as a selfie showing the full family of five—including her husband, Brian Fichera —all smiling together.

“How are these guys growing up so fast????” Dreyer wrote in her Instagram caption. She continued by reflecting on how her family enjoyed “an epic summer” and that she felt “so blessed to spend every day with this crew.”

“Here’s to an amazing school year!!” her caption concluded.

Fans echoed the NBC meteorologist’s amazement at how quickly time passed in the post’s comment section.

“In a blink of an eye and they’ll be off to college! Hold on tight!❤️,” one fan recommended as another agreed the boys are “Getting so big.”

One Instagram shared they "can’t believe your boys are growing up in front of our eyes” and thanked Dreyer “for sharing your family with us.”

Some of Dreyer’s fans who praised her “beautiful” family aimed their comments specifically at her oldest child, who “has grown so much.” Calvin “lost the baby face and has become a little young man.. all so cute.. even Mom and Dad! ❤️,” one Instagram user wrote.

Another agreed that the 7-year-old “is so sweet the way he takes on the big brother roll!!”

“Beautiful, happy family. Love to see that. Have a great year boys! Luv how your oldest is looking out for his lil brothers,” yet another fan commented.
