It is a false narrative, that antisemitism root is in others, and in no way in the Jews. So your question does not make any sense.

It is Jews who have to change to get rid of antisemitism, not others, and at least in two directions - abandon a habit to name everything they don't like as antisemitism, and get rid of traditions, habits and behaviour others account as incompatible with a normal society.

Your Jewish baby would hold his breath until he himself get that all antisemitism he could find is in him and his etnicity traditions, habits and behaviour. Unfortunately, he will eventually die, because Jews will prefer to keep all shit they used to, than to save their own baby. And of course they will blame others in his death.
