Part of the purpose could be to reaffirm from the start, the necessity for the mother to bend to the will of the establishment with the raising of her children. A subliminal form of conditioning, a token ritual if you will, bowing in supplication to the supremacy of the authority consensus. Logic dictates that she then bow to their conclusions on other related matters such as vaccinations, dietary recommendations, and medical "treatments" which disallow the considering of alternative possibilities (not controlled by the pharmaceutical complex). Just a thought. The purpose could be far more nefarious and specific.
