What is "sibling shape"? More generally, what precisely do the data look like and precisely what code did you try and precisely why did not that code do what you want? Otherwise this is only marginally different from "my code doesn't do what I want". On the face of it, total number of siblings = number older + number younger and so forth, so "+" appears to be all the Stata you need here. generate nsiblings = nyounger + nolder and variations on the same theme.
