Lol! Wait until the twin competetive thing kicks in emzy! This was the biggest problem with my two. Wouldn't say they were any naughtier than their siblings, but it was times two so may have seemed that way at the time. But this over the years this issue has caused me the main concern. Mainly from the one that regarded himself as an "underdog." This continued right through to college. Now as adults, the "underdog" eventually sees himself as a different entity, not as part of a set.
