I am a parent of 2 young children both with classic PKU. What we do at meal time is I make a veggie/fruit based meal; then on the side I will grill a chicken breast or fish/steak for myself and my husband. Here is an example of a typical family dinner-
All of us eat this:
steamed broccoli salad with ranch (ranch dsg made with mayo, and non-dairy creamer) cantalope,strawberries small baked potato. kids would split one with butter and chives, ranch kids will drink their special juice with meal
me and my husband:
may have different dsg, and have a portion of grilled meat/fish in addition to above
Kids were taught very early that meat is not healthy for them, but IS healthy for us. All of us need protein, right? So I explained to them that mom and dad get their protein from food and they get their protein from their special juice. Hope this helps.
