🦖🐾 READY TO ROAR was a ROAR-SOME success! 🐾🦖

Today Ms. Janine and our little explorers went on a PAW Patrol Dinosaur Rescue Adventure! 🚨🦕 We dug and excavated dinosaur eggs, discovered dinosaurs, tackled our rescue obstacle course, danced and stomped like dinos, and finished the adventure with a very special visit from Chase! 💙🐾

Thank you to all of our Treetop families who joined us today. We loved seeing our little rescuers in action! 🌳💚

📸 Did you take photos or videos today? TAG in your posts and stories! We would LOVE to see and share your favorite moments!

Something new is underway at The Treetop… 👀🌳

Spent my morning getting creative and working on another little project for Once Upon a Treetop! 🎨🍂

Being a small business owner means you’re constantly dreaming, creating, fixing, changing, planning and figuring things out as you go. Some days you’re the owner, some days you’re the designer, and some days you’re knee-deep in craft supplies. 😂

It’s definitely a challenge, but seeing an idea come to life makes it worth it.

Stay tuned… can you guess what I’m working on? 👀 And... can you say a 🙏 that it works? 🤣

🍦🧪 Today was ALL about ICE CREAM in S.T.E.A.M. with Ms. Janine! 🧪🍦

Our little scientists had the sweetest morning learning through hands-on fun! We read an ice cream story, explored ice cream sensory play, created our own colorful ice cream crafts, and then got to work on the coolest experiment of the day… making our very own ice cream! 🤩

We measured, poured, mixed, shook and watched science turn simple ingredients into a delicious frozen treat! 🍨✨ And of course, the best part was getting to EAT our experiment!

Learning is always more fun when you can taste the results! 💕🌳
