My 17 yr old granddaughter left her mum (my daughter) when she was 11 to live with her dad. She didn’t see her mum for 2 yrs but when mum was pregnant with a little girl, grandaughter wanted to be involved. She sees them once or twice a month now but there is no love for her mum. She is cold towards her and only really sees her because if her half sister, who she adores. I feel so sorry for my daughter who is heartbroken about their relationship. How should she (and I ) approach her and ask where she’s gone wrong. .?
