Introducing Matteo Tomaz Dos Santos!

Proud mama Kristin Dos Santos took to Twitter Wednesday afternoon (February 23) to share a sweet photo of her new little boy, with the caption:

Here he is! Little Matteo. Thanks for all your sweet msgs! I’m in love.

Kristin and her husband João, who welcomed her baby boy this weekend, are also parents to 1 ½-year-old son Luca.

What a cutie!
