Baby walker?

I know that they arent really recommended because they can delay development and all that, but im kind of wanting to get one so i can easily stick her in something when im in my backyard for example or in the bathroom trying to shower. Her excersaucer and jumper are way to big to move around the house wherever i need them and she gets super impatient just sitting on a blanket, even with toys. Do you think it would be okay for just those short windows of time when i need just a couple minutes? Any other suggestions?
