When Beth Kendall's son Wilder was born, he was immediately rushed to a special care unit after being starved of oxygen.
He suffered a type of brain injury, known as Hypoxic-Ischaemic Encephalopathy (HIE), a condition which affects one in every 1,000 births.
Two years later and Wilder, who is from Poole in Dorset, is doing well, but not enough is known about his long-term prognosis.
Researchers at the Princess Anne Hospital in Southampton are fundraising so they can carry out additional work that will give parents a more detailed diagnosis.
