So this might be a really random concern but I'm very musical myself and am desperate for my 21MO to sing but nothing yet
The closest I've heard is her shouting 'carcarcarcar' which I think was her trying to sing the wiggles 'toot toot chugga chugga big red car'
she's quite rhythmic when she wants to and will copy actions to songs quite well and sometimes even does we will rock you accurately. I should add as well that she's only really 'taking off' with her speech in the last few weeks. When did your kids sing? Does this mean she probably won't be musical? I'll obviously love her just as much even if she's tone deaf haha but just curious.
