Inner child work and trans folk

This might be a really stupid Q but how you therapists navigate inner child work or child envisioning when the “little child” brings up discomfort or gender dysphoria for client ? I usually have clients visualize themselves as a child or look at a picture and I’m honestly hesitant to do this if they envision a body that doesn’t match their gender. So I’m open to critiques or criticism here, but would rather have tangible assistance / ideas to navigate!
