This is (sort of) light-hearted because I love my kid to bits, but since the end of November he has sung Jingle Bells every day, multiple times a day, and I simply cannot take it any more.
We’re talking near-constant singing, from morning to night.
I have tried ignoring it, (light) consequences, and just reminding him that it’s annoying, but to no avail.
What are your strategies for this type of repetitive behaviour (common in small children I know!)?
