keep out from under one's feet: o que isso significa?

Imagine you don't have anyone to leave your child with at home and have to take him to your work. During the whole time, however, your child doesn't seem to wanna leave you alone. He is always getting in your way. So you say: Keep out from under my feet. I'm very busy.

When you ask someone to keep out from under your feet, you're asking them to leave you alone, to stay out of your way, to stop bothering you. It happens all the time with my mother at home when she's in the kitchen. I go into the kitchen while she's working to get some water or something, but she keeps asking me to keep out from under her feet because I'm getting in her way. That's it for today. Take care!
