I'm so worried, my heart is racing a million miles an hour. Leon has vommited 4 times today, he's lethargic and pale, hasn't done a poo since yesterday (which is unlike him) and his nappies have hardly been wet He doesn't have a temperature but I've been told several times that often babies don't get one when they're sick anyway. I called the MCHN hotline and she said to get him checked, it could be gastro, so I've called the locum doctor to come out and see us. They said they'd call when they were on their way here so who knows how long that will be. My mum who I live with, had gastro a few days ago, so I'm pretty certain that's what it is. What's likely to happen with gastro? What else could it be?
