I think it's too soon to say that Christina and Claire are bosom buddies, but at this point they are at least aware of each other.
On Christmas afternoon James was playing with all his Christmas spoils while the girls were cuddling with Brian and me on our bed. Christina was with Brian and Claire was next to me. Christina left Brian and purposefully inched her way over next Claire. It started off very sweet with the girls cuddling with their heads together. As time passed Christina got more "affectionate" with Claire, putting her hand on her face and then soon after her leg and then she tried to climb on her at which point they were separated!
It's fun to see Christina interact affectionately with her sister. She interacts with James but in a more playful and laughing kind of way, and James is usually the instigator. So to see Christina actively interact with Claire is so sweet. I think they will be close little girls and it will be interesting to see the roles reverse as Claire grows up. For me, the hardest part about caring for Christina is that I always worry about her. It's not the long nights, or the around the clock feedings, or the constant medications. Her physical care just needs to be done, and while it can be tiring and seem difficult at times, I look at these tasks like the Nike slogan, "just do it". What really keeps me up at night (so to speak, because it is her feedings that do!) is wondering and worrying if she is happy and if she will be happy. And I often ponder how James and Claire will be with sweet little Christina when they are all grown up. At such a young age, James has already shown great kindness and patience with Christina that is beyond his years. So I hope that Christina will have forever friends in her siblings, at this point Claire and James. And seeing their kindness to her gives me hope that she will be happy and that helps me to worry less.
