Big Sister / Little Sister T-shirts

My sister recently gave birth to her third daughter, so it was a perfect time to design some new sister t-shirts to celebrate the new arrival! The big sister and middle sister were very proud to let people know about their new little sister!

We weren't surprised to have another girl in the family. After all, my mother had 3 girls, and her sisters had all girls. One of my sisters has 2 daughters, and the other now has 3. Any boy born into this family would get more attention than he could handle!
