Hi there, I am PKU just like everyone else.LOL I do have a healthy 10 yr. old girl.(NO PKU)
I planned her to the day of almost conception. I went on diet 2 months before even trying to get pregnant.
If your biological clock is ticking.LOL like mine was the formula ,and food was easy to deal with.
I counted all my food intake daily. Blender full of formula.(Phenex 2,Mangos,ice,and 7-up) It was like a slushie. Its not easy with the formula,but when you see and feel the baby it just makes it worth it.
I did go to a store called Walgreens. They have braclettes (terry cloth) that you wear on your wrists.It pushes against pressure points that take away morning sickness.
