My LO developed hives on her face yesterday and today and it was immediately after nursing so I'm inclined to believe it was something I ate.

The only new thing I've eaten in the past few days is scallop and shrimp so I think that's what is causing the hives. However, we did try broccoli with her yesterday (for the first time) as well. But I suspect that the shellfish is the culprit since its a more common allergen.

I know it can take 2-3 weeks before dairy exits your system, but how long does shellfish take? Should I pump and dump? Is there anything I can do to help get it out of my system faster? (e.g. chug water?)
