I can help you with this. In the end pictures and video are the only way to preserve memories. And life is short. I lost my nephew at 22 months old and have only a handful of pictures of him. No video. From that day on I promised myself I would never be in this position again. With that said, I jumped head first into photography and now years later I follow my kids marching band around--shooting every game, every show, every festival, every parade and every kid within it. I give away thousands of images every season. And just when I was questioning the time, effort and money I put into doing this for all the parents, we lost a band kid. My daughters best friend. Now one of the last images I took of her rests on her tombstone. At the funeral, almost all the pic on display were mine.
So learn a lesson from my life and never ever worry about taking too many pictures. Take more! You will never regret taking too many. You will always regret not taking enough.
Photographs are priceless. And with that said, print what you want to preserve!
