How precious is this photo?!
And look at the smile on that little baby's face! He has a tiny dimple!
Grayson will join two-year-old brother Gavin Guess to turn this former threesome into a foursome!
Proud mama Marisa said:
"My son Grayson is healthy and such a sweet baby. I feel so blessed and excited to see both my boys grow up together."
She also admitted however that labor was "so intense and the hardest thing I've ever done in my life."
Of course husband Griffin was as proud as can be, saying:
"I was so proud of Marisa, she is such a strong mother, [it's] amazing to watch her grow into such an empowering mother. She was amazing!"
We're also so happy the parents shared this picture of three-day-old Grayson with us!
