Around 1,000 surrogate babies have been born in the UK over the past two decades. In recent years, half of them have been born to serial surrogates: women who've been surrogates more than once.
Last night saw a channel 4 documentary following the journey of a number people embarking on surrogacy. It examined the highs and lows, the complex legalities as well as emotional upheaval of the journey.
Jill Hawkins, Britain's most prolific childless surrogate, has given away seven babies over the past 18 years. Is it finally time for Jill to wean herself off her need to have babies for other people, and start living her own life?
Janie and Peter have been trying to have a baby through a surrogate for three years. After several bad experiences in the UK, Tammy Lynn in Kansas is now having twins for the couple, and they've travelled the 5,000 miles to be with her at the birth.
In Essex, Amanda - a first-time surrogate - is having a baby boy for Stephen and Olga. With Olga and Amanda not always seeing eye-to-eye, we witness the complex and emotional journey that leads to having a surrogate baby.
Carole Horlock, the world's most prolific surrogate, tells the story of her career-low: when she discovered that a baby she had given birth to had been accidentally conceived with her own partner. What did she decide to do about the child, and has she ever regretted that decision?
