It's nice that he can do this with his child, but it's probably not realistic for most people, especially those who work 9-5. Also, add another child to the mix and suddenly things aren't so easy!
That’s true, although I think there’s still a good lesson in there about making the time count, regardless of how much time you have to give. An hour of real undivided attention is probably better than spending a whole day together but being distracted most of the time.
Well, you can of course make the choice to not add another child to the mix, if you feel like Derek's way is a good way to parent.
