N.B.
Just an added reminder---any upset stomach complaints should be followed by some comment about why it's happening, something like, "all that gum made you feel bad". This is what we call "a teaching moment". My son ate a bunch of my bcp's when he was 2. Dr. said he'd be fine, just remind him every time he throws up that pills made him sick. For at least 3 years after that, you could ask him about pills, and his response was always the same--"pills make you sick!"
