Hi,<br/><br/>Now I am teaching my kid to wash his hands.<br/><br/>Letting him stand next to the wash basin, I say to him, "Stretch your hands" or "Stretch your arms."<br/><br/>My intention is to let him push his arms forward and open his hands.<br/><br/>Which one is correct?<br/><br/>Is "<i>Reach out your hands"</i> correct?<br/><br/>Thank you in advance.<br/><br/>Stephen
