With summer heat waves, it can be hard to stay cool when you’re outside. Our favorite way is to add water play to our routine. This week started off with a Mermaid Swim Party.

Every day, I like to do a hands on activity with Mila. In the summer, that usually happens first thing in the morning. It’s a great way to set the mood and guarantees extra learning for the day!
A win-win right?
Since Mila loved the beach sensory play activity earlier this month, I thought I’d bring those themes back.
The best part, we used actual water this time!
A mermaid swim party wouldn’t be complete without these:
- Sensory tray
- Barbie mermaids
- Resin letters
- Sprinkler
- Seashells
- Water
- That’s Not My Mermaid by Usborne
This activity was pretty simple to set up. The hardest part was getting the sprinkler in the hose.
All I did was setup the sprinkler (which wasn’t that hard at all), grab the items for the sensory bin, place them in, and fill up the bin with water. That’s all!

Before I let her play with the bin, we read a book. I believe reading books everyday is so crucial for a child’s development. They’re able to expand their vocabulary with every new word they here and start becoming familiar with sight words.
For this activity, we read That’s Not My Mermaid from the Usborne series.
It was a fun stepping stone to get her describing the differences of our mermaids during the activity. Plus, Usborne books are so educational. We love this series and find different ways to learn from it each time.
I would recommend the That’s Not My series to anyone!
After we read the book, I showed Mila her sensory bin and let her do whatever she wanted with it.
She went wild!

Between the water, the mermaids, and the sprinkler, she thought it was the best activity. I loved the way she reacted to it all. It’s always so much fun to see her growth through play.
I’d love to say I watched her the entire time, but she played with this activity for two hours. Yes. You read that right THREE HOURS.
For some reason, she really just thought this was a blast. We did different educational activities like talking about the resin letters and talking about the differences in the mermaids. She also loved pretending and making up stories about them.
At one point, Mila even got into the sensory tray to try to play with them more.
Eventually, after three hours, Mila was finally done with this activity and playing with the the hose. I was amazed that she was so engaged. It allowed me to wash the dishes, change the laundry, and tidy up. Of course, I kept checking on her, but it was hot!

Honestly, it makes me so happy to see how much she loves to play, use her imagination, and be outside. If creating simple activities helps, I’ll keep doing just that.
What are some of your favorite ways to beat the heat waves? Do you stay inside or like to play with or in water too?
