My family has a tradition of meeting at my great-grandpa's cabin the week after Christmas to lounge, watch movies, play games, and eat good food. This year, we added Rock Band to the mix, and (if I do say so myself) I became a semi-proficient drummer. Those high school years of bass drumming paid off.
Another part of the tradition is putting the babies in the sink for a bath. These two little girls are exactly two months apart. Last year they looked like this.
This year, they were walking and babbling, and almost good friends.
