Husband wants stay at home wife

My husband has a great job that he loves, and we aren't struggling at all. We watch our money very well, and have all the things we need. I'm thinking about getting a job at a boutique or something small, just a few days a week just to have a little extra money. My husband is a good man, and doesn't think I need to work, he feels that's his job and doesn't want me to stress, since we are currently TTC. I understand him completely,  and I do get out of the house so it's not like I'm cooped up lol. Just wanted to see some of your opinions in stay at home wife/moms. It is a job itself! :)
