4 year old insists she doesn't want ballet lessons. Do I make her?

As the title says, my 4 year old daughter is adamant that she doesn't want to take ballet lessons. However, this kid LOVES ballet. She is constantly asking me to watch her "dance". I signed her up for some lessons at a local community centre and ordered her a costume. When she found the costume and I told her what it's for, she lost her mind insisting she doesn't want the lessons and will refuse to go. Spent half the day in tears when I told her I already paid for it and she needs to try one term before deciding she doesn't like it.After a bit of conversation trying to figure out why she's being so stubborn about it, turns out they sometimes play "ballet class" at the babysitter's house, where the sitter's 9 year old is the teacher and it's "hard".We had a talk about how some things are hard to do at first but once you learn they're so much fun! I made comparisons to swimming and skating, both activities she hated at first but now can't get enough of. I tried telling her the class will be for little girls just her age and they're all just leaning and it'll be hard for all of them, but fun. She'll make friends! I even told her that I talked to her bestie's parents and they're going to sign her up too. She is still adamant that she doesn't want to. Do I force her at this point? Drop it and get my money back before the refund window closes? Help please, looking for advice. via /r/Parenting https://ift.tt/2XJxTN9
