When she very first came to see us in the hospital, she looked into his cot and said "Baby James. Silly James!" - with such affection and lent in to stroke him gently.
Since then, the first thing she says when she's come into the house from nursery, swimming or being out with Grandparents is "James". She's happy to give him kisses and stroke him, and when he cries she says "it's OK James".
She'll look on with concern and interest when we change his nappy (the only time he really, really cries), and only once or twice has she said "No James" when she's wanted my attention when I've been busy feeding him.
I think she's going to be a wonderful big sister... until (from personal experience) they hit the teenage years!
