Who reads at bedtime?

Have any of you seen reports of this study from 2014 that states that children gain more when fathers (assuming a father is available) do the bedtime reading?

“When sharing a book with their child, they would often link events in the book to a child’s own experience. For example, when a ladder was discussed in the book, many fathers mentioned the last time they had used a ladder to climb up on the roof or use it for their work. Mothers did not do this. Mothers focused more on the details in the book and often asked children to label or count objects or identify colors.”

I think it's interesting that it has cropped back up--thanks Scary Mommy!)
