English does not allow a subject to be repeated in its own clause.
The pronoun she cannot repeat the subject, doctor, in the first sentence or the subject, Andrea, in the second.
Do not add a pronoun even when a word group comes between the subject and the verb.
The pronoun it cannot repeat the subject, watch.
Topic fronting
Some languages allow “topic fronting”—placing a word or phrase (a “topic”) at the beginning of a sentence and following it with an independent clause that explains something about the topic. This form is not allowed in English.
The pronoun them repeats the “topic,” the seeds. The sentence can be revised by replacing them with the seeds.
