My 10 month old daughter loves this play tunnel. She has a blast crawling back and forth and even pounding outside (it makes an adorable hopping noise for her). She even tried using it as a walker rushing around the playroom. It's been her favorite toy for months, and now that she's an adult, she's using it in new ways to entertain herself. The quality is great (always happy with Melissa & Doug products) and the color scheme is perfect for our pastel colored playroom. That's a hit!
