Is there anything I can do to negate the colicky effect of cow's milk protein so I can have dairy while I'm breastfeeding?

With my first, I had to avoid dairy because the milk protein made her colicky. I learned from my pediatrician that this is actually quite normal in babies. Now that I have my second one, I just can’t stand the thought of no dairy (no cheese, no sour cream, no ice cream, no milk – I eat this stuff ALL THE TIME!!) this time around. So I was wondering if anyone knew of A) dairy products that have less of an impact (i.e. I can eat butter on toast with no problem) and B) milk substitutes and/or anything out there that helps process the cow’s protein in ME so that, by the time it gets to him, it doesn’t bother him.

Remember that it’s the protein, not the lactose that upsets babies, so Lactaid and things like that won’t help. This is something I will ask my pediatrician about at our first appointment but that’s still at least a week away and I’m hoping to get help now! :-D
