She gets no privacy. No personal time. No quiet naps. No toys of her own. He is set on being a part of every waking moment (and some of the sleeping ones, too) of this little girl's life.

I assume that the day will come when he won't be thrilled to find her in the middle of his room playing with his matchbox cars.
And I'm guessing she'll eventually be grossed out by his antics, jokes, or smelly socks.
But for now, he is the clown,
and she has the best seat in the big top.
