Dylan Dreyer's adorable son, Calvin, is 10 months old — and the TODAY meteorologist couldn't resist sharing a pic of her little guy celebrating his big day.
"Our 10-month-old cheese!!! Time flies when you're having fun!" Dreyer wrote next to a pic of Calvin whooping it up with a bowl of baby food. Look at that happy grin!
"Just when we think today can't possibly be better than yesterday, he always surprises us. Then we start feeling bad for today because we know tomorrow will be even better!" Dreyer wrote.
Dreyer and her hubby, NBC Nightly News cameraman Brian Fichera, welcomed Calvin, their first child, last December, and it's been a blast watching as the adventurous infant enjoys each moment of his first year — like when he met his great-grandma in July, and attended his first Red Sox game just two months later.
Calvin also surprised mom on-air for her birthday — in a Superman onesie, no less!
As for Dreyer, she's rated motherhood the "ultimate joy."
"I don't care how tired I feel," she gushed to TODAY last January. "I see his face and I just fall in love every single time I look at him."
And, really, who could blame her?
Happy 10 months, Calvin!
