-reshape- is your friend here. See the example below:
*----------- begin example ----------------
clear
input long id byr
2 1973
2 1975
3 1954
4 1965
4 1967
4 1969
end
label variable byr "birth year of child"
sort id byr
by id : gen bord = _n
label variable bord "birth order"
/*what to do with when two siblings are born*/
/*in the same year, e.g. twins?*/
reshape wide byr, i(id) j(bord)
list
*--------------- end example ------------------
(For more on how to use examples I sent to the Statalist, see

Hope this helps,
