Is there such a thing as a safe baby walker? My 9 month old is eager to learn to walk!

Although traditional walkers are highly discouraged by KK Hospital, most of us here actually grew up in them and are walking perfectly fine. I guess it's up to each individual preference on it. I personally am not using the traditional walker because I have a 7 year old daughter and she plays rough with my 7 month old son. Wouldn't want her zooming her brother around then house in the walker
