I'm late on this- but i have to say we struggle with diet too.
We have a one green and one orange vegetable per day rule- so i try to do that for lunch. I don't like to rely too heavily on the low pro foods as i'm worried one day we wont' have them and i wonder how much nutrients they really provide. But i need them because i need the calories!
A typical diet for my 2 year old – I do a 62.5mg phe for her meals and 31.5mg phe for each of two snacks
And try to aim for 600 calories (because she is getting about 400 through formula)
One slice of pku raisin bread with butter (14mg of phe and about 120 calories)
One serving of So Deliscious Cultured Coconut Milk (28 mg of phe and about 140 calories i think)
and then her formula (she gets 30mg of formula ) and I add cows milk in to reach my phe for breakfast.
I still buy babyfood jars for her so i always have a quick veggy on the side when i'm running late
120g of pureed squash (@0.31mg/phe/g =37.2mg of phe and 40 calories i think)
