Puberty with Power guide for girls 9-14 showing complete toolkit with meal plans and trackers

If she's approaching full puberty

This is the guide you wish you'd had...

She's asking questions you're not quite ready to answer. Her body is changing, her emotions are all over the place, and you're Googling "when will she get her period" at midnight.

Maybe she's already started her period and you're both figuring it out as you go. Or maybe it's coming soon and you want to be prepared.

The Puberty with Power Guide gives you both the knowledge, language, and tools to navigate this journey with confidence - from first periods to hormone balance to understanding her monthly cycle.

  • The puberty book is absolutely brilliant. The colours are both calming and vibrant, and the simple, well-organised layout really encourages you to keep reading. Everything is broken down into clear sections, making it easy to understand and follow. It’s incredibly relatable, and I love the clever way you explained the process as a stage production, with each part playing its own role. I’m very impressed with the whole book. Well done — I would highly recommend it.
