Occasionally DD will spit some out or her drool/spit up  will come out darker from it and get on her clothes or burp rags. THEN, when I wash her clothes, I will find random black spots on OTHER clothes...ughhh so frustrating!!! I hate this stuff. Anyone else having problems like this? It's ruining all of DDs cute clothes
