My 2yo ds fell onto a giant patch of poison ivy at the park this evening? What do I do? I took him home and stripped him in the doorway. His clothes are in a bag. I soaped him down in the shower and he's now soaking n the tub. I have no clue what you're supposed to do. I am not allergic to poison ivy. I can practically take a bath in it and not break out. Hopefully he is the same. Do I wait and see if he gets a rash?
