She even revealed that while she was making strokes of her own, so were her two older sons, sharing pictures of them with mini putters playing rounds of their own.
And in another adorable video clip she posted, Calvin really got into the spirit of the game, enthusiastically whooping for his mom every time she sank one in.
It got to the point that she gave him the club to try it out himself and they high-fived after he scored, with Dylan writing: "Getting a feel for the greens @edgewoodtahoe
"Calvin's got it down already! Glad my caddie is also my cameraman #caddydaddy."

Another said: "Man he is goooood at it! A pro already?! Awesome job Calvin," and a third commented: "He is so amazing and it's so wonderful that you can share this experience with him!"
She concluded her time at the championship with a beautiful series of sun-drenched family photos by the beach at Lake Tahoe.
