Quote by Orson Scott Card
Parents always make their worst mistakes with their oldest children. That's when parents know the least and care the most, so they're more likely to be wrong and also more likely to insist that they're right.
Summary
This quote suggests that parents often make their biggest mistakes with their firstborn children. During this phase of parenting, they may have less knowledge and experience, but their love and concern for their child are at their peak. Consequently, they are more prone to making errors and are also more adamant about their opinions being correct. This can stem from their desire to provide the best for their children, despite their limited understanding of parenthood at that time.
