Yeah thanks MadB, using S26 formula for the top up, and have been for about 3 months (just so I can do my doula work and jet of at a moments notice). So guess it isn't a dairy allergy. Feel guilty for using the Heinz jars and Rafferty's now. Going to get sorted and cook up some batches of veggies I think. At least it will be easier to find out if any one item of food is causing the problems.
