One of the most enjoyable parts of being home with my kids is watching them develop their relationship as sisters. As Ella becomes more verbal, they're interactions are becoming more complex.
The fighting started first and it was cute (at first) when they would argue over toys. Now, they have all out screaming, hitting, biting fights and it's not so cute. Then they started to play together. At first, Samantha would include Ella in her pretend games, instructing her what to do. Now, they both join in, although it's still usually Sam's idea. It's not unusual for me to see them both sneaking around the couch, then one will scream, "Bear!", and they run, screaming through the house.
Then, my favorite, the love, began. They hug each other, are concerned when the other one is hurt. Last night, Ella woke up crying. I went into her room, to try to calm her down. Half awake, she cried, "Sammy? Sammy?"
"Sammy's asleep in her bed, right over there, Ella," I said.
She quieted and rolled over, "O.K., night Mommy."
Right back to sleep, comforted by the presence of her big sister.
