Michelle, it's one of those things that people comment on just for the sake of commenting I think. But really, if they stopped and thought for a minute, they would realise why you are having them close together =) I fully expect to get similar comments if and when we are lucky to have another one ourselves.

Of course the advantage is that when they are all close in age and grow up together, there is a special kind of closeness between them. They go through things at almost the same time. We have both situations in our family ... two girls close together and one boy some years later. I love him to bits but we are almost different generations, whereas my sister and I have a lot of shared memories and other experiences that make for a close relationship later in life.
