In 1965, the typical married father barely spent half an hour each day actively engaged in childcare, according to the best time-use data we have1. Today, Millennial thirty-something dads typically spend more than 80 daily minutes changing diapers, reading and playing with their children, driving them to soccer practice, and going over homework.

...

While fathers spend more time playing sports with their children, mothers spend more than twice as much time providing medical care, planning appointments, and taking care of the so-called mental load of parenting (i.e., not just driving your kid to the birthday party, but also remembering that classmate’s birthday party existed in the first place and buying a present ahead of time). In fact, the more stressful the childcare activity is, the more likely mothers are to do it.

I thought this was really interesting because whilst a 4x increase seems like a lot it works out that the average Dad is spending ~50 minutes per day solo with the kids but Mum is spending double that time, ~106 minutes per day, solo with the kids.
