Helga, we're a couple of years past that first grief, so let me say what I wish someone had told me. The guilt comes in waves, and it hits hardest at birthdays and school plays you watch on a phone screen. What eased it for us wasn't time on its own. It was a change in what we could offer. When we lived nearby, we were the babysitters. Now we're the grandparents with a house by the sea, and every summer the grandchildren come for two weeks that they talk about all year. We give them less of our time and more of our attention, and I think, in the end, they got a good deal. It still aches. But it's a different ache, and not a regretful one.
