But the biggest benefit of all was in the lives of my older children.

That's how it seemed to me, too. When my second child was born, I was working for Facebook so I got a nice chunk of paternity leave. My wife was breastfeeding, so she was basically with the baby all the time. The most helpful use of my time often wasn't to be the second parent in the same room as the baby, it was to go do something else with our 2-year-old so that he could still do fun stuff that the baby wasn't ready for, and so that at least my wife only had to deal with one kid at a time.
