Tengan un nuevo hijo para el viernes/ Have a new kid by Friday

The idea of quick results in parenting feels both hopeful and challenging. I'm curious whether this approach is based on specific research or personal experience.

Parenting often feels unpredictable, so I wonder if these methods work universally or are better suited for certain situations.

I'm interested in whether the emphasis on quick behavioral changes aligns with or differs from more gradual approaches I've seen elsewhere.
