Sorry but if she's struggled to bond its on her to get help! I was extremely unwell when pregnant with my son and contracted sepsis. I was in hospital close to a month, on antibiotics for almost a year, blood tests went from daily to every two days, weekly, fortnightly, monthly, and still, now he's 11, my blood still isn't right and I'm considered extremely high risk of contracting it again during my recent surgeries. I couldn't breast feed, couldn't walk as my muscles deteriorated, my weight dropped to that of child, I was unwell for a long time........ never once did that affect my bond with my child.
Sorry I know we're all different but she's not the only bloody one and doesn't seem to realise how fortunate she is in terms of never needing to worry about maternity pay and sick pay with a child to look after. She also has plenty of money and opportunity to get the best in terms mental health care.
I'll say it again. She is a brat.
