For how much time in a day i should put my baby is a walker?

According to most websites, you shouldn't place your baby in a walker for more than 20 minutes a day. Personally I feel that as long as he's not in the walker for long periods of time, it's fine. A walker isn't where mummies should put their babies in for them to self entertain while she does her house work. That's not safe. It should be under supervision because baby would be mobile and bumping into everything in the house.
