DSD has been to several groups, all of which she hasn't stuck to, the latest being swimming. I paid for swimming lessons (£30 ish) for DSD aged 9 and half way through the second set of 10 lessons, it became 'too difficult' as she was asked to stick her bum in the air to do a butterfly preparation exercise. So she didn't return. Now asking for music lessons at around the same cost, AIBU to say no?
