I don't know how I feel about it from that perspective. I didn't consider that there might be some children who would inevitably feel left out.
My daughter already had everything that they brought her, so she came home and gave her pack to her baby brother
On the other hand, I don't know how I feel about not doing something kind because you can't do it for everyone. Usually (not always, but usually) when one of my kids gets something the other doesn't, they share or are happy for each other.
I would think especially for children 8 + that they could understand. I don't think a lot of people realize how resilient children are... it might bother them for a day or two but I don't think it's something they're going to grow up and remember as a defining time in their life when they didn't get something.
