I had twin sons (they are 32 now) who were born seven weeks early. They were a handful to take care of at first since they were preemies, but for some silly, idiotic reason I just kept thinking it would get better, say when they were six weeks old, then it would be better when they were a year, and on and on and on. It didn't get better just changed with their ages. It was very nerve wracking when they started driving, sad when they left for college, and exciting when the first GC was born. It just goes on for a lifetime and you never stop worrying about them.
