In the early hours of the morning, she gave up trying to sleep at all.
After five minutes he gave up trying to sleep and got out of bed.
He went back inside and tried to sleep, but could not.
All I wanted was to go home and try to sleep.
"How can I keep him in his room during the hours when he should be trying to sleep?"
He turned his back to her and tried to sleep.
She sat with him for a while before going back to her own room to try to sleep.
She turned over on her side and tried to sleep.
She would say nothing more, so once again they tried to sleep.
I knew should go in the other room or just turn the light off and try to sleep myself.
