Sleepy

So my wife is at the end of 5 weeks. She has been getting great amounts of sleep, which is awesome Homework and PlayStation time (lol). But this question is for the mothers who have been down the road already. My wife sleeps when she gets home after work, and at night and she still wakes up feeling exhausted. My wife works super hard she is a RN. So is there anything that your men/family/friends could have done to help with feeling more rested ? Any input is great thank you all. Have a great day.
