Basically what the title suggests, he did it at nursery last week and got sent home. Was fine and happy, I took his temp and kept a close eye on him. Now, a week later, he's been sat on the sofa playing Animal Crossing with his dad and then randomly threw up a bit on himself. No warning, no gagging. He says he's fine, not had anything acidic for tea, he ate hours ago and he's got no existing health issues. It's setting off my parent spidey-sense though. Any advice would be fab.
