Girls, how do you let children who walk poorly go to the apartment?

Girls, how do you let children who walk poorly go to the apartment? My daughter can walk about 10 meters by herself, but she's small and doesn't understand where the sharp corner is or where there isn't one. I'm so afraid to let her go, she keeps grabbing my hand all the time ?How did you manage? Or does she gradually learn and walk with me holding her hand?)
