Another thing is there's the difference between getting a guaranteed reward that you want (two marshmallows) vs waiting for the unknown. What good is waiting if a kid could potentially have 15 minutes of fun time with a toy, but they instead wait for two gifts and all they get is a pair of socks? But I was also a kid who'd beg nonstop to open my presents early. I knew if I opened something early, that was more time with a cool game or something. If I waited, well, that was less time with the cool game. Plus most of the presents weren't interesting. There was just one thing I wanted in particular and the other stuff could be forgotten.
