CL, that must be very stressful for you Have you considered seeing a dietician at all? There are some that specialise in food allergies and intolerances and would be able to help you identify the exact intolerances and plan a diet which meets the nutritional needs. There is very little chance that your DD is lactose intolerant - it is so very rare in babies as to be basically non-existant, and if she were lactose intolerant she would not have been able to tolerate any breastmilk or formula since birth. It is however possible that she has other food allergies which have caused temporary damage to her tummy and therefore temporary lactose intolerance. It is also possible to have temporary lactose intolerance after a tummy bug. There is an article here that you might like to read which explains it better - Australian Breastfeeding Association - Lactose intolerance and the breastfed baby. Don't let the title put you off, not all the article will be relevant but it does explain lactose intolerance which you might find helpful.

It is possible that your DD has an allergy or intolerance to something in the dairy (not lactose) which is causing her symptoms, maybe cows' milk protein - this is where a dietician can be really helpful so that you can identify that. Another thing to consider is that soy has been linked with a range of other issues too, and that more than half of the people who have a reaction to cows' milk protein, do to soy also. It is possible to meet the calcium needs without either dairy or soy, it can just be a bit more tricky. There is a list of high calcium foods here - Vegetarian Network Victoria - Complete Nutrient Summary .

All the best CL.
