Not sleeping good

My husband is really tired when he got home this evening. He didn't sleep so good last night and he woke up so late this morning and went to work around 8 o'clock. He slept so early this evening and I hope he will have a good night sleep. I am worried about him if he don't sleep so good at night. All of them are sleeping right now except me. I am here trying to finish my job hehehe..
