First I wanted to thank you for taking the time to help us with your site. It was really a big help for me.
My story, in brief, is here in case you feel it may help others.
I have a three years old daughter that suffered from constipation/fissures since she turned 1. I tried everything to fix her constipation issue but nothing seamed to work. After I looked into your page, I decided to try cutting on the milk, to see if it would help. Going to soy milk was a miracle, her constipation ended as well as her fissures.
But my discovery didn't finish there. I went to Spain for a month, and I couldn't find soy milk there. So I started her on milk again to see what happened. I was amazed to see that the milk was not causing her constipation anymore. However, when I came back to the US, the first day she had milk, she got constipated again.
The only difference I noticed was that the milk I used herein the US was fresh milk, while in Spain she had long duration milk (ie: Parmalat). I went to the supermarket and bought Parmalat ...and this fixed it again. She doesn't have any constipation if she uses this long duration milk.
So I don't know the reason, but I know for sure that there is something in fresh milk that causes her constipation reaction and fissures.
Again, thanks for your and the other writer's help!!
The original poster sent me the following description. If you have more information, please send it to me.
All I could find so far was that whey may be the difference between the two milks;
The two main protein fractions of milk are whey (20%) and casein (80%), and an individual can be allergic to one or both. The casein is the curd that forms when milk goes sour, and the whey is the watery fraction, which is left after the curd is removed. The whey fraction contains mainly alpha-lactalbumin and beta-lactoglobulin and is the most allergenic fraction and therefore causes the most clinical problem. The whey fraction is altered by heat, and so the whey sensitive person may be able to tolerate evaporated, boiled or sterilised (Long Life) milk & milk powder.

I still need to find a link between whey intolerance and constipation...will let you know if I do.
