friend birthday party

The boys had a couple friends over for a late night to celebrate their birthday's. Because my boys' birthday's are a day apart, a put up streamers for Ethan in his choice of color. Later that night, I take Ethan's down and put up new streamers for Isaac. They do much of the celebrating together, but I want to make sure that each boy feels he is an individual and each has his special day. Hence, Ethan and Isaac have their own cake in two different flavors/colors.
