I loved the Mini Duna when Peaches was tiny, and she loved to nest under the platform. Even the wheel was fine for the first few weeks, but after that I found it quite easy to disconnect. The next wheel I got was a Savic Rolly which was ok but sooo squeaky!! I now have a junior Wodent Wheel and would happily use it in the Mini Duna for another baby Syrian. It's just right and not so huge as to overwhelm the little one
