I cut dairy and soy 2 months ago. Yesterday around lunch I ha a few Oreos (soy) and we went out to dinner. I made sure there was no dairy in my meal but no idea about soy.

How long would it take to know if LO is reacting. He seems totally fine. Hoping I can add soy back in ! I'm not even sure if he was ever reacting to it but eliminated just in case.
