How can I make my husband feel special?

I think while dealing with my own postpartum I forgot how hard this was on my husband. I'm a Phlebotomist in nursing school. This pregnancy was an oopsy. I was nervous because I needed to keep working because they have a 75% tuition reimbursement from my job and I'm depending on that and being a nurse is my everything. My husband was a sou chef before this and he quit his job to be a sahd so I could continue work and school. None of his friends are sahd so he lost all his friends. He keeps the house clean, cares for our son, and always makes sure dinner is ready by the time I get home and he's been really depressed. Plus he agreed to go to therapy to work through his trauma and that's been hard on him. What can I do to show I appreciate him.
