big sister and big brother t shirts and gifts are all the rage these days. i can understand it, even though i only have one child at the moment, you better believe the second there is another one on the way, i will plaster my daughter in big sister and "going to be a big sister" t shirts and apparel! so far, one of my meant to be kind of funny designs seems to be taking off the best. it's the "i'm the big sister/princess design." it's available for all places - little/middle or big and basically just plays off the princess angle.
