The answer is no.The data on ur passport are yours and not his and this is permanent residency we r talking about. So as long as u r including ur child in ur application,u hv to get a valid passport for him.if u hv followed this forum closely,u wud hv read of cases where even newborn's passport are needed So to be on a safe side,try and get a passport for ur son because that will be his only valid means of identification for now.
