We have been on it since about 2 months old. At first I noticed when she would spit up it kind of had a super light pink/purple tint to it. Her GI doesn’t think it’s a concern (thinks it could just be from it being a compound prescription) but if I happened again she wanted me to take in a sample to make sure it isn’t blood. It just happened again for the first time in months. It’s very hard to see, that’s how light the pink/purple is. I am just wondering if anyone else has had this happen before?
