text: A 23-year-old mother-of-two is at risk of being banned from seeing her own children - because she refuses to stop drinking and partying. The woman, named only as Gemma, has two children under five by two different fathers and handed both infants over to her 52-year-old mother Debbie when they were four months old. Now Debbie is threatening to ban Gemma from seeing the children at all, after discovering her daughter's penchant for legal high, MKat, and because she suspects her of stealing.

'She [Gemma] isn't fit enough to have them. She doesn't care.' Debbie, who stepped in to care for the children after social services threatened to take them away, says her daughter's constant drinking and partying is getting out of hand. She also claims that Gemma, who is unemployed, stole an iPad from one of the children and sold it to fund her party lifestyle. Although Gemma says she did not steal the device, she admits to stealing money and other items from her mother in the past. 'From around the age of 13, she went off the rails,' says Debbie. 'She was drinking beer and having underage sex. Upset: Debbie reacts after hearing the results of Gemma's lie detector test - which revealed she did steal . Furious: Debbie, who has looked after Gemma's children all their lives, says she will ban her from the house . 'With the children, she was excited about being pregnant but gave up about four months after having them and then dumped the babies on me.' As a result, Debbie, who appeared alongside her daughter on The Jeremy Kyle Show, has been left to bring both children up alone. Now at the end of her tether, Debbie says she is preparing to ban Gemma from her home and from seeing the children - because she can't trust her not pinch their possessions. Upset: According to her mother, Gemma prefers drinking and parties to work and motherhood . 'I don't know how you could do that to your own kid,' adds Debbie, who also revealed that Gemma's children call her mum and not grandma. 'She doesn't care. She doesn't care at all and I feel awful about it because at the end of the day, they're my grandchildren and I love them. 'She's missed out from day one. She doesn't put them first. She knows she needs to grow up and stop drinking and taking drugs and partying.'
