She had us fooled!
"First daddy daughter swim in Lake Michigan-a right of passage for any Mitten baby ✋"
We can't be sure which daughter is in the shot with Dax, but it's probably three-year-old Lincoln, who is a little older to go swimming in a lake than younger sister Delta, who is one and a half years old.
When they're old enough to decide for themselves, we're sure we'll see more pics of the two!
Until then, this is all you get, folks!
