Ingested off lotion?!!

#1stimemom I left my 2 year old in the bedroom after i applied off lotion on him. I didn't know i left the off lotion in the bed. I was in the kitchen, i was worried since it's too quiet in the room i peek and see him licking in the opening of the off lotion container. I was in a panic and bring him directly to the nearest local hospital yet we were advised to be observed for 2hrs and sent home. I'm still bit worried about the harmful effect to my son of the off lotion. Any of you have experienced same?
