My son was diagnosed with an allergy to cow's milk at 3 weeks of age. Now, before you all freak out , no I was not feeding him cow's milk from a bottle. He was getting the proteins in my milk and then reacting to them. I was told by his ped "You are going to have to be soo careful" and sent home to find out what careful meant. I researched it and found out as much info as I could. I have dropped all milk proteins from my diet (lost 40 lbs in the process!) and finally found a small amount of foods I can eat. I cannot go out to dinner for fear of getting proteins (tried it twice and we both paid for it for days!). I have been so careful but have managed to get milk in my diet 4 times since early Dec. My son will be 3 months on Sunday. It has been a long, hard road. I have been fighting to continue breast feeding (we have had many other problems as well). Today, after two days of happiness, my son woke up and was not really acting like eating. He had 5 or 6 bowel movements in a row. I told my mother I thought something was wrong and in his next bowel movement there was blood. This, along with fussiness, is our clear cut sign that we have found milk. Here is my problem. I have been so careful for the last 1 1/2 and I cannot figure out where the milk has come from or even if it is milk this time. My ped acts like I am crazy when I bring him in and she can't find anything wrong with him but I don't know what else to do this time but go see her. Does anyone have any advice on allergies or suggestions as to what else this might be? He's up and crying again, so I must go. Any help is appreciated!
