Can I use walker for 7-months old baby?

It's best not to use a walker for your baby. Safety experts and health professionals strongly discourage the use of baby walkers, because of the number of accidents and injuries they cause. Baby walkers are dangerous because they give babies extra speed, extra height, and access to many hazards. Also, walkers won't help your baby learn to walk. Using one too much may even delay her walking independently. The use of baby walkers is a huge concern for many countries. In fact, in Canada their sale has been banned since 2004.
