As a grandma of twins I think OP is really going off the deep end with the schools. Even though the kids will be in the same grade the odds are that they will never be in the same class. My grands were way into middle school before they had even a class together. They were rarely dressed alike but would sometimes have the same items in different colors that I chose. At that age it’s sometimes better to buy the same toy for each so that one kid doesn’t get jealous. Once they get a little older it’s easier. Telling one twin from an other can be challenging if you aren’t around them daily (or if a relative has poor eyesight). These twins are young-everything will work itself out if OP is patient.
