Hi, Di: My first grandchild was "unico iho" (lone child) for four years. Then his sister was born. The difference in gender made a big difference and choosing presents was easier. My grandson was also prepped up to be excited for the birth of a sibling. Would your DH's second grandchild be a sibling of the first? Perhaps, if you did something with the firstborn to welcome the next baby? I made a little stuffed doll from an old baby sock of my grandson for his sister and did the same thing with them for their baby brother. Would that sort of thing help you out? Otherwise, perhaps, you can get the second child a present similar to one of those which you gave the first.
