Just over eight years ago, we were blessed with the arrival of our first child, Sophia, who was born healthy and full of life.
Like all babies she had the standard newborn heel prick test to check for signs of rare disorders and illnesses. While I wept like a baby, thinking about my little girl being prodded, she hardly even flinched and then it was over.
Three days after bringing Sophia home, I got a phone call from a number I did not know that would change our lives forever. On the other end of the phone was a nurse from the Royal Children’s Hospital in Melbourne who told me that the results of Sophia’s heel prick test were irregular, and would require further testing.
The very next morning, we returned to the hospital where further tests confirmed that our baby girl had Phenylketonuria (PKU), an incurable and potentially debilitating rare disease that I had never heard of.
While Sophia’s diagnosis is rare, PKU in fact impacts one in every 15,000 babies born in Australia, so 20 or so mums a year get a similar life-changing call like I did.
PKU is a metabolic disorder that prevents the normal breakdown of a protein found in most foods, which causes protein by-products to build up in the blood stream. This build-up prevents the brain from developing properly. Progressive intellectual disability results if PKU is not managed from early infancy.
The only way to manage PKU is through a strict, lifelong low protein diet and special formulas. For those with PKU, their diet is restricted to just 1-8 grams of protein a day, compared to 46-64 grams of protein a day for those without PKU. While we all know that meat, fish and eggs contain protein, there’s protein in everything from bread, fruit and vegetables, to even my own breast milk.

At the point of her diagnosis, I had to limit my breast feeding and Sophia’s main food source came from a special formula. At each feeding time, I had to first feed Sophia her required dosage of formula followed by topping her up with breast milk, which was a very hard and painful process.
