At night time, I try to put all my little people to bed, the adults are no problem, although they wake up every few mins and wander about even when they still exhausted or tired.... my kids however will not go to bed and run about the house at night when the parents are asleep.... how do i get them all to go to bed and stay there til they refreshed?

Also, it's hard to get them out of depression, whats the best way to get them out of depression?

Thanks in advance.
