Hi! My daughter born 10/05/06 is hyperphe. I am also hyperphe and my son just turned three an March 17th has classic PKU. We take my daughters blood once a month and her levels have always been within the normal range. She is not required to be on a special diet or drink the formula. We continue to take her blood monthly until she is one year old. We see a terrific genetic doctor in South Carolina, where we currently live. Originally from Michigan too, we now live in Hilton Head, South Carolina.
