Lucca has been amazing with Jackson so far, we couldn't ask for more. I was nervous about how the queen would respond to a stranger invading her castle (as her pediatrician perfectly put it), but she loves him. She gives him kisses, reads him stories, holds him and tries to give him milk and apple juice. When he's not called "brother" she likes to call him Jack. We know they will have a pretty special relationship and it's been melting my heart to watch it form already.
Best big sister in the world.
