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.”
