A woman from Rotherham who has been a surrogate mother twice - is calling for urgent changes to what they believe to be outdated surrogacy law.
When Kate became pregnant she always intended to give the child to its parents, Tracy and Pete from Portsmouth.
But, under UK law she could have changed her mind at any point and kept the baby as her own, because she gave birth to the child.
The law states that the woman who gives birth has the right to keep the child, even if they're not the genetic parents.
Which is why Kate and Tracy say the need for better laws is more important than ever.
