whoseGotMyEyebrows - she hasn't been asked. 
And I admitted the PFB bit BUT I don't think there's anything wrong with being PFB in this respect. Oddly enough, when my child is upset my first thought isn't "I hope MN don't think I'm being PFB if I care about this happening to him."
What's so bad about wanting your babysitter to put your child to bed when he is tired and not have her then get him back out because he wasn't asleep before she left the room?
Or to not want to come home and find him screaming with exhaustion and asking to go to bed, something she admitted had been going on for a long time?
Or to expect her to either ring and tell us she didn't know what to do with him or even tell us that when we rang her, rather than fob us off with the clearly untrue statement that he was asleep in bed?
Look at it this way. If I had posted to say that she/me/DH/whoever had left him in bed to cry and scream for a prolonged length of time you would have all been up in arms about how cruel it was to leave him for so long.
To me it's no better to keep him out of bed and let him cry for a prolonged length of time while begging to go back than it would be to leave him in bed for a long time when clearly distressed.
FWIW, I have posted one incident on here about usually very good relationship that is eleven years old. I bet there's not a single MNer who can honestly tell me they have never been annoyed, reasonably or not, at someone they have had a close relationship with for that length of time.
If he had still been up but happy, rather than crying, I wouldn't have minded so much.
