Ok. so may be mold was not the correct translation of “Taqweem”. I think the nearest translation could include “proportions” as part of its meaning. So Ahsan-e-Taqweem means Best of mold, proportions etc.
A human child is in best of the mold, proportions etc. just as a human grown up is or just as Hazrat Adam was.
