A woman has been labelled "cruel" in a parenting forum online for admitting she does not want her stepdaughter to call her mum.
She admitted on Mumsnet that she doesn't know how to tell her husband.
"My hubby and I have been together 10 years, he has a 11 yo [daughter] and has full custody of her (last time she saw her mum she was about 1)," she wrote on Mumsnet.
"I also have 3 sons with him. She is the only one who doesn't call me 'mum' in the house."
"She asked me a couple of weeks ago if she could call me mum like her three brothers.
