Sacha is 4 and lives in Brighton. He has a rare genetic disorder called 2q37 deletion syndrome. This means he is likely to grow up with cognitive and physical difficulties. But the range of possible outcomes is wide, and there are many factors that can improve or worsen the prognosis.

Defying expectations, Sacha has responded remarkably well to intensive blocks of paediatric therapy: the first enabled him to stand for the first time; the second got him walking; in the last, he learned to climb and descend stairs. Every round of therapy was a tangible boost not only to Sacha’s development but also to his happiness and confidence. Without these therapies, it would have been a much longer struggle for Sacha to reach such milestones.
