My elder daughter is 12 and Grade 5 piano and flute and began guitar in an afterschool club at school last year. She gave up violin when the teacher moved house but still has two violins which she occasionally gets out.
My ex has facilitated her music and has bought all of the instruments and paid for lessons but I obviously had to facilitate the lessons for flute; the piano teacher comes to the house.
My younger daughter elder daughter’s half sister, has now started piano at school. Elder daughter has locked piano as her dad has instructed that my younger children cannot use the piano or have use of the other instruments.
