I think our child seems to like us both "equally" these days, though it is clear some days that nothing Daddy does is correct, and mommy would do it better/properly.

I can also see that when she works overnight he tries to outright punish her, by ignoring her, when she returns.

But those kinda things aside I don't see anything like your story there. I guess it goes to show that kids, and personalities, are so varied.
