Sorry this is long...need your opinion based on your experience with food allergy...
At about 1 month I took DS to the pedi because I was worried about how upset he was all the time and seemingly uncomfortable. At that time the pedi told me that because LO was gaining weight and all vitals were great, it was probably colic and mentioned cutting down on dairy might help. At that time I started doing tons of reading about milk allergies. After reading, this also clued me in that he definitely had muscousy stools (FTM, I just thought they were nasty baby poops and didn't really realize his poo was abnormal). I cut out all obvious dairy and saw some improvement in his demeanor some days but no changes in the stool. Shortly after that he had blood in his stool. We went back to the pedi and he didn't seem concerned and again said he is thriving, he'll grow out of it and everything was ok.
LO has continued to have green, mucousy stools but has never again had obvious blood, only the one time. (I know there could be traces in there) In his entire 2.5 months of life, I only remember one yellow seedy stool during his first week. He eats well and no breastfeeding issues. Continues to gain weight and above 50th percentile for height/weight. All day he pulls his legs up and still remains very fussy/seemingly uncomfortable. No rashes, no vomit, no other allergy symptoms.
Long story short...I've also read that the f/hmilk imbalance has similar symptoms. With what I have described, does it sound like an allergy/sensitivity or an imbalance/something else? Even though my pedi is not concerned, I still feel like I should be doing more to help him.
