What happens if you are a baby and you have been converted by your parents does that make you still Jewish? by your Jewish parents that have adopted you and they convert you at a young age that the child is instable to realize of what’s going on with him and also make his own choices?
If a child undergoes a conversion, by means of adopted parents, he is given the choice upon reaching the age of bar-mitzvah of whether to remain Jewish, or to leave the Jewish faith and live as a non-Jew. If one does not object to one’s conversion, one remains Jewish, and one does not retain the option of leaving the Jewish faith.
