Do you use baby walker for your baby and Why yes and why no ?

I do use a walker. But i don't place my baby there for hours. Only when i needed that little help from the walker to care for my child while i cook or do something. Other then that, i will place baby on a floor mat for him to crawl or scoot. Prolong sitting in walker isn't good as it hinders with the development for walking. Baby will just mainly their body for strength to push around.
