Plot involves two parents with a baby. They are visited by time travellers from the future who tell them the baby becomes like a god in the future, the first superhuman. I think the name of the baby was Alexander.
The time travellers are here at their future leaders request, to begin his education while still a baby. The parents get increasingly stressed out as their baby / then toddler learns psionic abilities but acts like a normal baby.
Teleports the mother into a shop to buy him candy while she is not dressed. Shakes the father upside down to make coins fall from his pocket when he claims to have no money.
Eventually the child goes too far with some strange equipment left by his instructors, and he suddenly vanishes, never to return. The parents are relieved as life had become so difficult. Apparently the whole future time line has been wiped out.
