Tell him that you appreciate everything he does. Thank him for making your day easier by cleaning or doing certain things.  Being a stay at home parent requires a lot physically and mentally. It's exhausting and you never get a break. Try giving him one day out of the week where you do everything and let him rest. With your job, you get your breaks and lunches but he doesn't.  Tell him he can have a free day to do whatever he wants and not worry. You as a partner should support whatever it is he wants to do, even if that means he just wants to sleep.
