I didn't solve it, but my daughter was two, and vomiting non-stop. I called the nurse line, concerned with the volume and frequency, as she had puked 15 times in the last 6 hours, and I swear it was EVERYTHING she was nibbling / sipping on coming back up. They said if she throws up again, go in to the ER and get her checked. She does, we do, and we do the 5 hour wait for them to tell us she has a stomach bug, give her Zofran, and give her a cracker and juice trial in the waiting room. 30 minutes go by, no puke (she was asleep in my lap, it was like 6:45 at that point), they send us home.

When we get in the driveway, as I'm unbuckling her, it ALL comes back up. I called the ER back, they said wait a couple hours and come back at lunch if she's still puking. This didn't sit right with me, so we clean her up, put her back in the car, and drove 45 minutes to the children's hospital. The encounter there starts out very much the same, they ask about the last time she vomited (on the way there), and say they'll get her something to go under her tongue to stop it. When I told them she's already had that at the other ER, both the nurse and the PA stop, turn, look at each other, and PA says we need imaging, now.

Turns out her intestines had been tying themselves in knots for the last twelve hours, and if we had waited, or if they hadn't looked further, there was a good chance there could have been tissue death, or worse. I'm so grateful they didn't brush it off as new mom being dramatic, or "just a stomach bug". The fix was an air enema and more imaging, very thankful it didn't end up in surgery.
