By Anna Hodgekiss PUBLISHED: 07:22 EST, 14 January 2013 | UPDATED: 09:33 EST, 14 January 2013 A mother has lost 12 stone in nine months after her children begged her to take control of her weight. Annette Skinner, 46, shrunk from a size 32 to a size 14 after her son Alex came home upset that she didn't look like other mothers. Her daughter Kelly, 25, was also concerned her mother's weight would restrict Alex's upbringing, and he too would be bullied as she had been as a child. At her peak, Annette, from Walsall, weighed 25st 10lb. She says she was so big that people didn't realise she was pregnant with Alex.
