OK, this is a bit tainted with my own experiences and those of others around me but......every time I see a reflux baby now I consider whether or not its a cows milk allergy. Could it be that your kids do have a cows milk protein intolerance as babies and Juliette gets very little from you through your milk, but Zander got a whole whack of it through the formula?

K still refluxes when she has something with milk in it, she had some girl guide biscuits yesterday and has been refluxing ever since, but she generally has a dairy free life (as do I) and no reflux at all. It bothered her the most with the burning and such when I had heaps of dairy in my diet, then we went through the real shocker colic days *shudder*.

Just a word of warning though Sarah. From my experiences with three refluxy bubs, it *seems* to be harmless happy chucking until about 3 weeks old, then it turns nasty. Has happened every time. My guess from my kids is that it takes the system that long to work up to critical mass. So either if its caused by allergies it takes the body that long to reach the point of 'no return', or if its run of the mill reflux, it takes the stomach acids that long to develop the qualities to start to burn.
