Big hugs hun. I have had my boys in day care for quite a while now, and have used two centres in that time. NEVER has anything like that happened. It is true that the late afternoon is a busy time as parents turn up and want to talk etc, and mostly they are in mixed age group then as well, so the carers there might not be the ones from their room. I know this is the time that DS1 used to be most likely to have an accident (wet undies), as the carers might be busy when he needed to go to the toilet. But he was never left in wet undies - they noticed that it happened and fixed it. And a baby covered in vomit - come on. That would smell for one thing, how would they not notice. That doesn't seem right. Not at all.

I'm sorry hun, I know it's a huge PITA, but I would be looking for a different centre. You need to know your child is being well looked after and you have doubts you will just feel guilt. I hope you find somewhere fantastic. GL.
