This is a great toy for little one. We purchased this when our little one was 7 1/2 months old. She loved the various activities available on the front panel, and quickly started to use the walker to stand (note: she was already able to stand up by herself whilst holding on to something).
Obviously, the key function of this toy is to help Baby take her first steps. This works wonderfully - on carpet. As other reviewers have pointed out, the wheels slip and don't spin on slick surface (e.g., wooden floors). So when out little one started using the walker to walk (10 months old), its use was limited to carpeted areas of our flat. Worse, when she tried her luck on wooden floors, she lost confidence. Even on carpet, the walker was sometimes too fast for our baby.
Having checked reviews for other walkers, this seems to be a widespread issue with walkers.
Luckily, there is a solution.
I fitted the wheels with "homemade tyres". I put a few elastic bands on each wheel, kept in place by 3 thin strips of duck tape. Obviously, there is no need to ensure the elastic bands sit perfectly flat on the wheels. Quite the opposite actually, This set up does the trick nicely. The walker's wheels now spin properly on every surface, and our little one can go wherever she wants.
