I also wonder if I should buy a baby walker for my bb. I did some reseach on this and found some info from wikipedia:
Many parents believe that such walkers teach a child to walk faster, however, studies suggest that it is not true, and they may actually delay walking by two to three weeks.[2] These devices have also led to many injuries.[3][4][5][6] In fact, CPSC, American Academy of Pediatrics[7] and other organizations have issued warnings to discourage parents from using baby walkers.
In Canada, the sale of baby walkers was banned on April 7, 2004.[8][9][10] Canada is the first country in the world to ban the sale, importation and advertisement of baby walkers. This ban extends to modified and second hand baby walkers, including those sold at garage sales.[8]
