Teaching children to keep trying
Format: Kindle
I have read a few of Elizabeth Cole’s books, so I was pretty sure that this would be another great children’s book. I wasn’t disappointed. Advertisements REPORT THIS AD Nick is excited when he gets new roller skates, but he soon realizes that skating isn’t as easy as he thought. He’s about to give up when his dad talks to him about it. He gives Nick several examples of people, including his mom and his friend, who persevered and achieved their goals. It’s important to teach children that failure is part of life and that practice is important. This book does that well! Perseverance Makes me Stronger is told in rhymes and the illustrations are cute and colorful. It helps children to learn that failure is part of life, and we need to practice in order to achieve our goals.

Very realistic, beautiful pictures
Format: Paperback
For Montessori, this book is perfect. My daughter loves the children and the real pictures. She would take the book with her in our walks and point to the book when she saw something.

Leaves Skin Super Soft Without Being Harsh!
Style: Soap Saver
I wasn’t sure what to expect, but this Cleanlogic exfoliating scrub is amazing! It has the perfect balance—it exfoliates really well but doesn’t feel scratchy or overly rough on the skin. After using it, my skin feels smooth, refreshed, and so much softer. What I love most is that it actually lathers nicely with body wash, so it feels like a mini spa treatment every time I shower. Plus, it’s durable—I’ve been using it for weeks, and it hasn’t fallen apart like some cheaper brands I’ve tried. Another huge plus is that the brand supports visually impaired individuals with packaging that includes Braille. It’s a small thing, but it made me appreciate the product even more. Would I recommend it? Definitely. It’s affordable, effective, and makes my skin feel amazing after every shower.
