They absolutely love it! We sing some songs that they learn in children's church. Papa plays the (real) guitar while Joe will 'play' his own guitar.
Joy-Anne also wants to play kor kor's guitar so we have to convince them to take turns. While waiting, she plays the 'drums' instead.
She's absolutely adorable when she tilts her head and says in a very cute voice, "Now Joy-Anne turn ok??"
