The girls are getting older and starting to interact with each other. Xian (soon to be 6 months) and Tegan (just turned 5 months) have been hanging out for the majority of their long, long lives and are beginning to play together.
Today, they played with a block and Lulu, the alien in the foreground. Sage (almost 3 months!) is checking out the commotion caused by the "big" girls with a solid promise to be soon involved.
