They.

Lately…
he fusses and HE tries to fix it.
HE wrestles with Daddy and he growls and joins in.
he’s hungry and HE gives him bites of his food.
HE plays and he wants to be RIGHT in the middle of it.
he goes to the puppy bowls and HE tells him “NO, NO!!!”
HE laughs and he laughs right back. 
HE goes fast and he tries so hard to keep up.
he falls and HE makes it better.
HE loves SO hard and he gets irritated.
he dances in the car and HE thinks it’s hilarious.
HE get in the crib and he becomes overjoyed.

In a nutshell, they are already the most precious little playmates and
watching them brings me more joy than you can imagine.
