If he was home with you that day, then I would take him, but since you would have to take him out of DC for an hour or so, I'd say no.

I'm a firm believer of kids at funerals. We've never hidden death from the kids in our family, they've all attended friend & family funerals.

But it is a personal choice, each person views funerals differently, to me it is a celebration of their life and having kids there reinforces the cycle of life.
