Yes, the wheat and egg were fine. We don't have a family history of food allergies outside of celery! I am hesitant to try soy because I didn't fully eliminate soy and can't be sure there isn't an issue there. She mostly has a history of mucous in her stool and very very fussy, tummy hurting behaviors when I ate dairy. Some reflux symptoms, not spitting up much but a wheezing that was checked by her ped and unrelated to her airways or lungs. The fussiness subsided tremendously when I cut out the dairy and her stools became less mucousy and a bit more orange rather than green. She was a much happier baby so I've been sticking to the dairy free diet so far.
When she was about 3 months old I had a good amount of dairy and after a few days she became very miserable again, with the green mucousy poops. That was the main reaction. Other than that it would have been accidental and I didn't know if I had eaten any.
Since starting foods, her stools have gone all over the place. Huge, green, liquid messes that overflow diapers and require a bath and lots of stain treating of clothes or firm stools that are hard to pass. But I have not given her any dairy and most of her foods have been fresh or frozen and made at home outside of the cheerios and baby oatmeal.
