My son also has a dairy allergy. I continued to nurse him to ensure he'd get the fats he needed.....if your daughter only weaned a month ago she could start again if you both wanted.
Second to that, if she can't nurse or drink whole milk, I'd strongly suggest Almond milk or Hempmilk (can be bought at Fry's) for fats...we rotated between these two w/ my son during the daytime & he'd nurse to sleep. ANother thing you can do to boost healthy fats is buy some Flaxmeal, you can add that to almost anythign, and it is a great source of healthy fats...add to yogurt, oatmeal, soups, smoothies (stir in after blending)
One other thing - before you give her two much soy do a little research on Soy and estrogen / progesterone.
We tried raw goat milk to but my son wouldn't drink that. My brother & I were pretty well raised on goat's milk (lived on a farm), since my brother is also allergic to dairy. Worth a shot...it's actually easier to digest than cow's milk, even w/out an allergy (if he'll drink it of course)
