Dairy Question

aimalama

I originally went dairy free by the suggestion of my dd pediatrician when she was 1 month old.  The pediatrician suggested I go dairy free because my daughter was really fussy.  This was also around the time that she also put dd on Zantac for acid reflux.  I've always wondered if she really has a problem with dairy and I wanted to see how she would react now. 

On Monday I made spaghetti and put less than a teaspoon of parmesean cheese on top.  She breastfed on Monday night after I ate, 2 times in the night and then again in the morning.  She was fine all day yesterday at the sitter's house (she was drinking milk that was pumped the day before).  Last night I ate fried onion rings.  Today I talked to the sitter and she said that dd has been really fussy today - she is drinking milk that was pumped yesterday (after I ate the cheese).

 My question is:  is she fussy because of the cheese or the onion rings?  All opinions welcomed.
