Between the ages of 8 and 14, girls are expanding their social circles, figuring out what they love to do, and finding their voices. It's an exciting time! But this is also the time when girls report feeling a major drop in their confidence. Studies show that by the age of 14, girls are 30% less confident than boys, while eight out of ten girls say they want to feel more confident.

Bridging this confidence gap is at the heart of everything we do at Rebel Girls. That's why we created the book Growing Up Powerful, a bold, big-hearted guide to girlhood written by Nona Willis Aronowitz and illustrated by Caribay Marquina. As the editor of this book, I want to share some helpful takeaways for parents and caregivers of tweens and teens as they navigate the joy and messiness of puberty.

1. Help her appreciate her growing body

During puberty, a surge of hormones prompts a girl's body to change. Her shape might become curvier as her hips widen. She might gain weight or have a growth spurt. Her breasts will start to grow. All of these changes can certainly be jarring, and every girl's experience is different. For all of my sixth grade year, I remember wearing baggy sweatshirts to hide my growing breasts, yet in almost every tween movie I saw, girls my age were stuffing their bras with tissues. It was confusing!

What I wish I knew when I was constantly crossing my arms over my chest is the idea of body neutrality. Unlike body positivity, body neutrality doesn't mandate girls to love their bodies all the time. Instead, it encourages girls to respect what their bodies can do as opposed to what they look like. If your daughter is an athlete, point out how much stronger her body is becoming. If she's getting taller, comment on how cool it is that she can reach the top shelf now. And always guide her toward focusing on traits that have nothing to do with her physical appearance, like how kind, smart, and funny she is.

While creating Growing Up Powerful, we asked girls what they wanted to know about puberty. Of course, many girls asked about their periods, specifically exactly when they would get it. Alas, no one has a crystal ball, but you can ease your daughter's anxiety by helping her prepare. One way to do that is by creating a period kit. Simply fill up a travel case with the following essentials: a few pads, a fresh pair of underwear, and her favourite sweet treat-exciting milestones like this should be celebrated!

2. Encourage her to take care of her mind too

As hormones do their thing, you might notice your daughter feeling more anxious, irritable, or teary. Powerful moods are totally normal, but they don't have to be debilitating.

Just like any other body part, brains need some TLC, especially when it comes to handling big feelings like anxiety. Mindful breathing is one way to unravel anxiety quickly. Try this with your daughter: Take a deep breath in while counting to four, hold for four seconds, then let it out while counting to four again. Repeat as needed!

Lastly, remember this: Actions change first, then thoughts, then feelings. It's impossible to just think our way out of a bad mood. So if you notice your daughter is having a rough day, go on a nature walk, break out the arts and crafts supplies, or blast some Taylor Swift tunes and have a dance party-the sillier the moves the better!

3. Guide her toward fostering healthy relationships

As your daughter grows up, it's natural for family relationships to become a bit more complicated. But there are ways to deepen your bond even during what can be a tricky time. Ask each other questions like these at the dinner table, in the car, or during a lazy weekend afternoon:

• What's your idea of a perfect day?
• What's something you'd like to learn how to do this year?
• Tell me about a time you felt super proud of yourself.
