Dahlia and Milana have really hit their stride. They play together almost all the time now and Milana is learning so much from imitating (and forced learning - Dahlia is a hard task-master) her big sister.
Nothing unusual about two sisters playing together except there wasn't very much of that happening around here for the first year and even two. But they're certainly making up for any lost time. And it's so much fun for me to just sit back and watch and listen to all their escapades.
