Astrology can offer insight into children-related issues by examining the birth charts of both the parents and the child. Key placements to consider include the 5th house (representing children and creativity), the Moon (emotions and nurturing), and Jupiter (growth and expansion). By studying these aspects, astrology can reveal potential challenges or strengths in the parent-child relationship, as well as the child's emotional and behavioral tendencies. This can help parents better understand their child's needs, strengths, and potential struggles, offering guidance on how to foster a positive and supportive environment for their child's development.
