It has been 12 years since Lorraine Harris was accused and convicted of killing her four-month-old son by shaking him to death.
Another child - a son who was born as she began her sentence - was removed hours after being born and sent for adoption against her will.
Ms Harris spent 16 months behind bars, but she was not guilty. Her conviction was quashed in 2005 after medical evidence about "shaken baby syndrome" was thrown into doubt.
Her efforts to be compensated have failed, so this week she is taking her case to the European court of Human Rights. The case is likely to affect other people who have had convictions quashed but been denied compensation.
Mike Pemberton, the solicitor for Lorraine Allen - who has now changed her name after remarrying - told the Today programme that she hopes to get in touch with her second child in the future.
Mr Pemberton said: "My understanding is that the second child was adopted and there is no going back on that.
"Having spoken to Lorraine, her hope is that one day that child will decide that they want contact with her, and then make efforts to locate and speak with her so she can set out why things happened and how it occurred."
