we used a hand me down walker but not much. and its not recommended, some even ban its use. i agree that best way to teach babies to walk is giving safe space to crawl and pull themselves up. with walkers, its the wheels that works.
May napanuod ako sabi, giving walker to a baby is like giving a car to a person who can't drive. Possibility of magfa-fast and furious sila gamit ng walker is high.
