She knows her

I show ruby lots of pictures of her sister. She has mastered saying "Lila" but I usually have to encourage her to say it. Today was a different . I held ruby up to the mantle over the fireplace and said who is this? Immediately she said "Lila." This was the first time I didn't preface it with "this is Lila, can you say Lila?" She just said it. Perfect and clear. I got teary and clapped for Ruby which she loves. I am so grateful that he knows her sister. Who knows just how deep their bond is.
