Friend brought 3yo round today. Her child played with mine for 1hr. Then she says that her child has diarhoea and vomited yesterday. The DCs had already shared some food and played with the same toys etc. I am so cross that she didn't warn me as I would have postponed. I know it is crap being stuck at home with this sort of thing but FFS - why spread it knowingly? I doubt her 3yo is very good at handwashing so I imagine there were germs everywhere!!
How long before we know if my DC (and me!) have this bug?
