Can mithridatism be used to create immunity/anti-toxin for others?

Say there is a plant-based toxin that causes what is essentially a state of deep sedation but has no other real effects. In this world there is one animal that is immune to this toxin (the plant is part of it's diet). There are hybrid creatures that, if close enough genetically to that particular animal can be affected by this toxin but only temporarily. Any other animal exposed, human or otherwise would usually be affected permanently.

Now say a person developed immunity to this toxin through mithridastism (whether knowingly or unknowingly being dosed with tiny amounts of the toxin over time). A couple of questions.

1. If this person was a woman and she was pregnant during the time (or part thereof) that she was dosed with this toxin, could the child born also be immune?

2. Could the blood of the child or the mother be used to create an anti-toxin in the same way the blood of non-human animals is used to create real life anti-toxins, and if so is there a time restraint on how long after exposure to the toxin this could be done (as with creating real life anti-toxins the blood is usually taken after a period of weeks or months), both in terms of blood taken from the immune person and anti-toxin administered to the affected?

Basically, would it be possible for an anti-toxin to be 'stumbled upon' in this way if previous research into treatment for those affected was intentionally sabotaged and it is widely believed there is no possible cure (as it seems pretty obvious someone would have at least tried to create an anti-toxin or something in the past given that they know there are creatures with full or partial immunity).
