My dd 19 takes part in a sport that requires her hair be tied up in a bun. She's newish to this sport but is doing really well at it and is competing this winter. As well as physical skill, appearance is taken into account, so it matters that the bun is neat. To help her out in the beginning I did the bun but now I want to encourage her to do it herself. Cue a tantrum worthy of a toddler. I've just finished a session of trying to get her to do it for herself, keeping my voice low and calm & encouraging her. She's having none of it, is being bolshy & ranty, throwing her toys out of the pram. She said it was impossible to do it for herself, so I had a go on myself to try it (whilst she watched) and it was ok. She's still having none of it - it can't be done, end of! I'm a single parent and I'm guessing this is about more than hair-tying but I'm not sure what? What can I do to encourage a more positive attitude in her and get her to give it a proper try?
