Though obviously outdated, filled with sexist roles and clueless, self-absorbed parents, the creativity and whimsy of the "cures" of Mrs. Piggle-Wiggle manages to endure over time. As a 7 - 8 year old child, I adored these books, when I was young. I still find them fun, on some levels, though significantly inaccurate in their portrayal of both children and families. As was so very common in those days, any child's behavior that disturbed adults was deemed a "fault" inherent to the specific child and childhood. The whole concept of child mental health was treated as a joke, in those days, disconnected from the child's role within her/his family, or the result of his/her relationship with one or more parents.
Parental knowledge and behaviors were never questioned back then - everything was always the fault of the child - whether at home or school. Adults were always viewed as perfect, while kids were always entirely responsible for the negative attitudes and coping strategies they had adopted. Thankfully, 70 years after this book was published, our society is more sophisticated, recognizing child depression, anxiety, impulsivity, bullying, self-destructive attention-seeking, and other issues as the far more complex and serious matters that they are, rather than as laughable, superficial matters.
As an adult reading this book, I can see how the author uses Mrs. Piggle-Wiggle as an unofficial child mental health provider whom even the local MDs refer parents to, once they have determined that the identified "problem child" doesn't have a physical disorder. Now, as a professional mental health provider (MSW) and RN, myself, I find these Piggle-Wiggle books disrespectful of both mental health providers, with their specialized work/skills, as well as, disrespectful of the emotions and psychological/developmental needs of children. The message in these books clearly is that the feelings and perspectives of kids are superficial and trivial, thus easily "fixed" with a bit of "magic". Nothing could be further from the truth.
These books can be still be enjoyed by children and adults, even in our more sophisticated 21st century society. However, just like other outdated, classic books from the past (e.g. Tom Sawyer, Huck Finn) which contain rampant sexism, racism, ageism, abilitism, and other stereotypes/bigotry, these books must be discussed and "debriefed" with children who read them. These books would be excellent ways to open up dialogues with youngsters/classes regarding the mental health and social skill challenges that are commonly encountered throughout childhood.
Critical thinking skills can be stimulated by asking children to reflect on the hurtful/negative tags they have been labelled with by adults (or that other children they know have been tagged with), then asking them to consider all the reasons why they believe any child might feel or behave in those ways. Such discussions can encourage empathy, compassion, and a greater willingness to discuss mental health and social challenges that both children and adults encounter throughout life. This would do much to reduce the stigma surrounding mental health challenges, along with dispelling the shame that too often is heaped upon children who come from dysfunctional families.
