How awful! Gastro is the worst If you're worried then give health first a call or a doctor to put your mind at ease. Did you happen to see anyone else's poo? Was it a similar colour, lol I know gross but hey it's a poo & vomit kinda thread. But if the kids were the same then probably not too much to worry about. Could be the dregs of the day before's iron maybe. I hope you feel better ASAP!
