Last week the controversial issue of surrogacy was thrown under the spotlight when a British surrogate mother was left raising a disabled baby after the intended parents refused to take care of her.
The girl, who has a rare congenital muscular condition, was one of the twins. But while her healthy brother was taken home by the childless British couple, the girl was left with the surrogate because of her disability.
The little girl is now being raised by the surrogate mum and her partner, alongside their other children.
