Hi Ciro, I am a mom of an eight week old PKU daughter. I live in Florida, USA and here we visit the nutritionist weekly for a weight check and blood test to see how her levels are doing. After the first year it won’t be as often. She has special formula that I mix with breastmilk to make her bottles for the day. Once she starts eating food I will have to count PHE levels for different foods and track how much she eats to keep her PHE levels in balance. Do they do all this in Spain?
