I have kids. I love my kids, they are everything to me.
I remember when they were infants and at no point, particularly months down the road, did I ever think of having babies at home as a “this is so distracting that I can’t possibly focus on my work” situation.
As long as they are home with a capable mother, I don’t know why it would I be.
Maybe he’s just slumping like many players do and this is just a made up explanation that we came up with that doesn’t have anything to do with it.
