She shared a series of heartwarming snaps of the youngster beaming as he played on slides and tucked into a slice of cake during the Spiderman-themed birthday party.

In a picture, Ollie was seen smiling at the camera and had his thumb up.

Today star Dreyer captioned the post: “Thumbs up from Ollie. We’ve been celebrating birthdays and holidays since Thanksgiving.

“That’s a wrap and a fun fun finish. Happy party day Ollie.”

Dreyer, her husband Brian Fichera, and their two other sons Calvin and Rusty posed for a heartwarming snap in front of a chalkboard that read: Happy Birthday Ollie.”

Two red spiders had been drawn on the board next to the Spiderman head icon.

Fans rushed to comment to say that Dreyer’s son had grown up fast.

One said: “Ollie looking so grown up all of a sudden… I guess cuz he is a year older. Happy birthday.”

Another commented: “Happy birthday to Ollie. [I] Hope he has a super year! The boys look so grown up with their haircuts.”

And, a third commented: “He’s just an adorable little boy. Seems like he’s grown taller so fast. Not little anymore.”

Others posted that the Spiderman-inspired celebrations looked “awesome” and fun.

Dreyer paid tribute to Ollie as he turned three last week.

She posted a touching clip and said: “My sweet, sweet Oliver.. you’ve been singing and dancing to your own tune since the day you were born.

“You bring so much joy and love to our lives… thank you for being you.”

Dreyer and her husband Brian Fichera, an NBC producer and camera operator, are also parents to Calvin, five, and Rusty, one.

During the holidays, she revealed that Rusty had taken his first steps.

Dreyer shared an Instagram video that showed the baby toddling around her living room in pajamas with a blue pacifier.

“Come here!” Dreyer said in the clip as the little boy leaned on a couch for balance.

After Rusty takes a handful of steps toward Dreyer, the little boy falls into her arms and the mother and son can be heard laughing together.

“Good job, baby!” she said.

Dreyer’s adoring fans expressed their love and admiration in the comment section.

One said: “That’s the most first steps ever. [It’s a] truly blissful feeling evidenced in your voice.”
