I was thinking something like this would work:
```
add_child(parent, child):
    prev_last_child = parent->last_child
    parent->last_child = child
    child->parent = parent
    if (prev_last_child):
        prev_last_child->next_sibling = child
        child->prev_sibling = prev_last_child
    else:
        parent->first_child = child
```

But it now occurs to me that you could special-case it to only handle up to 2 children.
