We didn't find out Ben was allergic until he was close to 18 months. For supplements we use Bright beginnings pediatric soy drink. (You have to order it online though) Also we use Duocal. (The dietician suggested this;it is a powder you can mix in) He is just turning two so we also add step 2 soy formula to his soy milk. The hardest thing is not being able to give him cheese. We do use tofutti products. They have a sour cream and a cream cheese that is dairy free. It is really hard to find food that is dairy free, milk is in everything! Ben is also allergic to peanuts so it is almost impossible to find high calorie recipes for him. Good luck and don't be hard on yourself! <img src="i/expressions/face-icon-small-smile.gif" border="0">
