Learn with our partner organization: Pearl & Thistle

With this quick and easy download, Catholic parents can prepare OURSELVES for the start of our daughter's first period by:

➡️ learning the sequential signs of puberty for girls,

➡️ gleaning wisdom from both scientists AND Church leaders

➡️ thinking through education in age-appropriate stages

➡️ and grounding ourselves in the GOODNESS of our own bodies.


This would be great for you if: 

  • She's getting towards puberty age and you're wondering whether your daughter is ready to learn about periods (and what you might want to say to her!)
  • She's still young, you already know you've got some time before puberty hits, but want to feel ready-to-go when it's time!
  • You're not even necessarily thinking about talking to your own daughter, but you're wondering how period prep could be better, especially for Catholics who believe in the goodness of our bodies!


Sections include: 

  • Learning the Signs and Timeline of Puberty for Girls
  • Tips for Decreasing Anxiety through Preparation and Affirmation
  • Pacing Puberty Education through Teaching Her the Stages of Body Literacy
  • Beginning with Affirming the Goodness of YOUR body and your role as Primary Educator, Mom!


...Including valuable guidance from both medical research AND the Pontifical Council for the Family!
