Advice needed! DS has a music teacher that comes to our house each week, but he doesn’t really enjoy the lessons with her. She very lovely (slightly odd, but harmless!) … they just don’t connect and he hates his lessons. He’s just had a trial lesson with a guy this evening, which he really enjoyed and would like to switch over. What would be the kindest way to broach this with his existing teacher, and is there a generally accepted notice period??
