Mine certainly changes as my children get older, and my concerns are different for each of them.

DD1 to be honest I don't worry about too much now as she has grown intoa healthy, self assured, happy little person but I do worry that people will take her easygoing nature for granted. As a baby it was reflux, allergies and gut issues. She was a very sick little poppet.

DD2 was again the gut issues, but she also has extreme anxiety that will most likely be a life long condition she will need to deal with, so that is and I imagine will always be my huge worry for her - how she is going to cope in a world that at times overwhelms her so completely.
