1. Our son is currently being breastfed before we have our results back. He was born on the 17th of Oct and so he is around 3 weeks old now. If he does have PKU, would it harm him to not be on a strict diet ASAP?
2. I'm quite concerned about how he will develop physically on a strict low-protein diet, he came out into this world at 4.24kg(9 pounds 3oz i think) and I had the hopes that he would grow to be a big strong boy but now I'm not too so sure?
