2 years old Georgia could count to ten, she can recognised her colours and was even starting to dabble with French. But it was only when their bubbly little two-year-old took an IQ test that her towering intellect was confirmed. Georgia has become the youngest female member of Mensa after scoring a genius-rated IQ of 152.
She was crawling at five months and walking at nine months. By 14 months, she was getting herself dressed.
"She spoke really early - by 18 months she was having proper conversations," Mrs Brown said.
"She would say, 'Hello I'm Georgia, I'm one'. She was also putting her shoes on and putting them on the right feet."
Georgia was so perceptive that after one outing to the theatre to see Beauty and the Beast she solemnly informed her parents: "I didn't like Gaston (the villain). He was mean and arrogant."
Struck by the similarities between her daughter and Matilda, the title character in the Roald Dahl story about a gifted child, Mrs Brown began to worry about Georgia's future education.
She contacted Professor Joan Freeman, a specialist educational psychologist, for advice.
Professor Freeman applied the standard Stamford-Binet Intelligence Scale test to Georgia and was amazed to find this was too limited to map her creative abilities. She said: "Even at two she was very thoughtful.
"What Georgia did on some questions was of a higher quality than that which was necessary to gain a mark.
"She swept right through it like a hot knife through butter.
"I would ask her things like 'give me two blocks or give me ten blocks' and she would manage it as easily as you would expect a five-year-old.
"In one test I asked her to draw a circle and she did it so perfectly.
"Most adults would struggle to do that. Her circle was near to being perfect.
"It shows she can physically hold a pen well but also that she understands the concept of a circle." To the amazement of the family, who live in Aldershot, Hampshire, Georgia scored 152 points on the IQ test, putting her in the top 0.2 per cent of the population.
