constipation .... Prunes during intro phase?

[Guest guest]

My son is going into day 5 with no bm. We are on day 3 of diet, so he is eating

mostly

protein (cooked chicken, eggs). I made him eat 2 cooked green beans tonight for

a

little fiber. My first batch of yogurt is resting in the frig. I have no idea if

it will turn

out right or not.

We started this diet because of yeast concerns. Am I asking for trouble if I

give him

prunes this early? He is drinking plenty of liquids. I started him back on legal

magnesium and Vit. c today.

Thanks, A
