Controlled crying in CC is pretty rare, actually (I've worked in a couple more centres than Leash and have only ever seen once place that does it) for more than one reason:

* Most centres claim to follow home routines where possible
* Leaving children to cry is not best practice
* It stops other children from settling.

If they want to do it, and you're not happy about it, I will give you some ideas on who you can write complaint letters to to make them do it your way.

Good luck.
