Dear Annie: My husband and I are raising a surprise baby at a stage in life when we thought our child-rearing years were mostly behind us. Our older children are already teenagers and young adults, and while we adore this little one, I would be lying if I said the large age gap has not brought some unexpected emotions with it.

On one hand, this baby is deeply loved and has brought joy to our whole family. On the other, I sometimes worry that he will grow up feeling more like an only child than part of a sibling group. By the time he is old enough to really know his brothers and sisters, they may be off at college, building careers or starting families of their own. I worry he will miss out on the closeness and shared experiences that the older kids had with one another.
