Is this Mykelti or Christine?

So we(my mom & I) have started rewatching SW on Sunday afternoons/early evening, then we watch the new episode before bed. We're currently on the episodes with the anthropology students. There's a scene where they are talking to Annie about her experience in polygamy and there is this picture of Annie holding a child.

Do we know if this is Christine, one of her siblings, or one of her girls???
