And there is an issue with the agencies - if they are the ones that were placing the child into your home the playpen or mat should have been in your home the day before the child started not weeks later. You paid for the service and they didn't provide it. A 2 year old should be able to sleep on a mat in the same room as the older kids and it would be better to start him where you want him to sleep even if it takes longer for him to fall asleep.
