Back in 1995, my wife & I had a 5 month old son that died suddenly from SIDS. I can tell you that the photographs we have of Robby are some of our most prized possessions. This was before my photography days, so we have mostly snapshots and some photos from the local cheapo portrait studio. Nothing of great quality, but still priceless nonetheless. Our oldest daughter was 2 when Robby died and we’ve since had two more daughters. We all really enjoy studying those photos of Robby from time to time.
You definitely have a gift for photographing people. Don’t worry about getting the perfect shot, just do what you do. Any photo you make for this family will be a masterpiece to them.
