Hi Misty, the second site I mentioned (kellymom.com ) has lots of information, not only on no-milk diets, but on fussy babies and food allergies in general. Might be a good idea to read it, print it out for your doctor, and discuss it with him.
I don't think 1 week without dairy will be enough though. Usually an "elimination diet" (which is what you are doing) lasts for at least 2-3 weeks, more often a month.
This is what it says on the website:
"If you think your baby is reacting to a particular food, then eliminate that food from your diet for 2-3 weeks to see if babyâs symptoms improve. If babyâs symptoms do improve, then this food may be a problem for your baby. Eliminating a food for less than 2-3 weeks may not be effectiveâcowâs milk protein, for example, can persist in momâs body for 1½ - 2 weeks, and it may be another 1½ - 2 weeks before the protein is out of baby's system."
"Breastfed babies who are sensitive to dairy in mom's diet are sensitive to specific cow's milk antibodies, in the form of proteins (not lactose), which pass into the mother's milk. Cow's milk (either in the mother's diet or engineered into formula) is a common source of food sensitivity in babies. Cow's milk sensitivity or allergy can cause colic-like symptoms, eczema, wheezing, vomiting, diarrhea (including bloody diarrhea), constipation, hives, and/or a stuffy, itchy nose.
If your baby is sensitive to dairy in your diet, it will not help to switch to lactose-free dairy products. The problem is the cowâs milk proteins, not the lactose. Cooking dairy products may reduce but will not eliminate the allergens.
A significant percentage of babies with cow's milk protein allergy will also react to soy. Most dairy-allergic babies will also react to goat's milk or sheepâs milk. Some will also react to beef.
If you think that your baby may be sensitive to dairy products in your diet, remember that it can take 10 days to 3 weeks to eliminate cow's milk protein from your systemâallow a full 2-3 weeks of dairy elimination before evaluating the results.
If your baby is only a little sensitive to dairy proteins, you may be able to relieve babyâs symptoms by eliminating only the obvious sources of dairy (milk, cream, yogurt, butter, cheese, sour cream, ice cream, cottage cheese, etc.); you may even be able to eat small amounts of dairy without it affecting baby.
If your baby is highly allergic, it will be necessary to eliminate all sources of dairy proteins, which requires a careful reading of food labels. See the Hidden Dairy "Cheat Sheet" ().
If you've cut out dairy because your breastfed baby is sensitive to cowâs milk proteins, you may be able to phase it back in after a few months. Many dairy-sensitive babies outgrow their sensitivity by 6-18 months, and most outgrow it by 3 years."
I hope you and your doctor figure out soon what the problem is.
