DS is 2 1/2. He has one vomit, then another 36ish hours later, then 24 hours, then 12, then a flurry of pukes over a day/night, and then it follows the reverse pattern until he's well again. In between pukes, he's peaky verging on poorly.
He's had four episodes like this over the last year and we're now verging on getting concerned. Did/does anybody else's DC do this?
