was a 20 month old brought by mother for "vomiting".
Me: When did the vomiting start?
Mom: A half hour ago. He was with my ex. I think he might have gotten into some medicine.
Me: What makes you say that?
Mom: Well it was blue and green and had chunks in it. Nyquil is blue.
Me: Did you speak to the Dad to see if it was possible, or that he had been given any blue foods?
Mom: What?! There are no naturally occuring blue foods!
Me: Rainbow Goldfish? Skittles? May not be natural, but they come in green and blue.
Mom: Oh. I didn't think of that.
Note: the child had eaten a lot rainbow colored Goldfish crackers when mom checked.
