My daughter cries during breathwork; should she focus on an object instead?

My ten-year-old daughter struggles with sadness and anxiety. When she tries pranayama or breathwork, she begins to cry because the physical sensations feel overwhelming. The effort is too much for her. Her mother wonders if concentrating on an external object, like a piece of colored glass or a candle flame, would be a gentler method for her to handle her emotions. Her name is Swati and date of birth is 2nd July 2015 at 7 PM.
