Whatever.... the little girl has a dependancy on her Mother..comforting her Mother...so sad that she is in that role.
yet we have to accept the relationship both need and have.
The place we are born into is our life lesson..and so many people go on to live great lives despite to hardship...for however affluent a family may be...emotional hardship can exist
A suggestion
start a journal that one day she will have from you..make it a between you two..tell how you miss her company..tell her what you are doing..there is no need to mention her Mother..the sophisticated thinking will be in place..sadly at the loss of part of childhood joy..
in my career many children in my remit had hardship at home...almost all defended their parents..no matter what went on..its essential that they have "some" relationship.to loose that for a child is loss part of themselves..
Go buy a a pretty journal Sharon...mention how you talk to us about your pride in her musical ability..and I know your writing will be beautiful...speak from that big heart you have.
