Time to set another place at the table: Tiffani Thiessen‘s baby boy is here!

The Dinner at Tiffani’s host and her husband Brady Smith welcomed their second child on Wednesday, July 1, she announced Thursday on Instagram.

Son Holt Fisher Smith joins big sister Harper Renn, 5.

“Yesterday Harper got a little brother! We are so excited to introduce Holt Fisher Smith. Our perfect sweet little man,” the new mama captioned a photo of the sweet siblings.

“We feel incredibly grateful and blessed at the moment. We couldn’t have imagined how much joy and happiness this baby boy has brought us already,” the couple tell PEOPLE exclusively. “Harper especially is loving being a big sister and can’t get enough of him. We’re living in a wonderful baby fog right now and perfectly content.”

Shortly after sharing her wish for another baby, the former Saved by the Bell star’s dream came true when she announced in January she was expecting.

“We could not be more excited about extending our family. Harper is beyond thrilled to have a playmate!” they told PEOPLE at the time.

Days later, the family of three cut into a gender reveal cake and found out they would be welcoming a baby boy to the mix.

Thiessen — who showed off her baby belly while reprising her role as Kelly Kapowski during a sketch on the Tonight Show — kept her fans updated throughout the pregnancy, sharing photos and sweet moments on her blog.

My heart could not be more full of love for these two. #weareblessed

“We couldn’t be more excited. And Harper … is she ever. Every day she asks me, ‘Is he ready yet Mommy?’ ” the mom-to-be wrote in a March entry. “It warms my heart to see the excitement and love she has for this baby already. Every day she kisses my belly. She tells her baby brother all the time that she loves him.”

Harper can't get enough of her baby brother. #Familytime

Her children are so adorable. Congratulations to the family. I also love both of her children’s names 🙂

She still looks the same as she did in “Saved by the Bell”—so unfair! I love the name she chose. Its different and unique without being “goofy”. I don’t think the kids at school will be able to tease him about his name like some other celeb kids.
