So on Friday we went tree shopping! I had no money to tip the guy who placed the tree on top of my car. So I decided to buy my 5 yr old a hot dog from food truck something that I never ever do. Needless to say he was throwing up and had diarrhea that night around the clock. None of us slept. I thought it was food poisoning. He’s better today but now my 8 month old seems to be having the same reaction. Not as bad but some Puking and little diarreah . I’m keeping him hydrated. Should I wait for it to pass like it did with my oldest or should I contact his Pediatrician????
