Support Tummy Time & Vision Development
This high-contrast water mat is a wonderful way to encourage tummy time with your little one. Newborn eyes see the world as a blurry place—black and white patterns are scientifically proven to stimulate early vision development.
Your baby will love pushing the water around and watching the colourful sea creatures float, enhancing their visual focus, motor skills, and hand-eye coordination.

I received this mat for my little one almost 6 months ago and love it! So much so, I brought another one this month for a girlfriend and her baby! It is the perfect distraction and when bub is getting heavy and only wants to be carried. We will often sit down and play with the mat together... Until Bub is happy for me to stand up and stretch!

I am the grandma and I ordered it for my grandson who lives in Darwin. As you can see he is still very young but he is starting to interact with the activity. He loves tummy time and also enjoys sitting on it while kicking his legs and mummy holding him.

My little ones loves her mat! It’s been a great tool to keep her entertained for longer tummy times! We also like using it outside with a little bit of water to add another dimension of sensory play!

5 Stars! Exceptional Customer Service & beautiful products I had an amazing experience purchasing from Young Wonderer and want to express my sincere gratitude for the excellent communication and customer service I received regarding my recent order, which included the Under the Sea Sensory Water Mat and Ziggy the Zebra. Although there was an unexpected delay for Ziggy the Zebra due to Customs, the team was incredibly proactive in providing updates and was clearly doing everything possible to resolve the issue quickly. I truly appreciate the multiple solutions offered, including the upgrade to Express Post, which ensured this Christmas gift for my new niece arrived before Christmas. Both products are beautiful and well made. The transparency and empathy shown, especially during the busy holiday season, truly stand out. It is clear that you genuinely care about your customers. I will certainly be shopping with you again and highly recommend Young Wonderer to anyone looking for great service and reliability.
