I agreed to babysit for a friend of a friend (and her friends children) recently, there were 6 children in total, youngest 8.
Our mutual friend gave her my phone number and everything was arranged via text. I got to the house at the pre-arranged time and the parents left straight away. As they were walking out the door one mum called over her shoulder, 'Oh X had Down's Syndrome btw'
I have no problem with that and would have happily babysat anyway but AIBU in thinking I should have been told before? It wasn't like babysitting half a dozen 8-13 year olds, it was like babysitting 5 8-13 year olds and a 12 year functioning at about the level of a 3 or 4 year old. He tantrummed when the other children wouldn't watch what he wanted on TV, when the sweets were divided out 1 each and he only got one and would not go to sleep! I had no idea about to interact with him as no-one told me!
Really not sure if IABU? but do feel very annoyed I was thrown in at the deep end as it were...
