Well, she's had her first lesson anyway! Today she went to her first 'toddler ballet' class in a local church hall. She loved it. To the extent that there were big heaving sobs because we had to leave when it finished. At least we're sure it was popular!
I don't like to come across all 'pushy parent' but she seemed pretty good at it too. OK, she didn't want to pretend to be a witch, and she absolutely cannot skip, whatever she told the teacher! But she concentrated very hard and nailed quite a few of the bits I never would've thought she would. Very proud.
