My brother is a SAHD and loves it. However, he also takes it extremely seriously, and I want to encourage you to do the same.
- Every day, he gets up before his wife to make her hot breakfast, coffee, and a packed homemade lunch.
- He manages ~100% of the kid stuff.
- He does a lot of DIY work around the house to save money on the trades.
- He does 100% of the errands and provisioning for the family during the week so that the weekend can be completely focused on having fun.
- He also handles 100% of the housekeeping and almost all the evening cooking.
- He takes personal fitness extremely seriously. He has commented only half-joking that he means to be a trophy husband, and he has very much accomplished that.
He would not have it any other way and I'm incredibly proud of what an example he is. When I retire and become a SAHD myself, I want to emulate what he does. (Although my wife also won't be working.)
I should also say that parenting attitude matters a lot in this. Being a parent of little kids can be a lot of trouble or less a lot of trouble depending on your attitude. In our families we practice benign neglect. We do stuff with the kids and take them fun places sometimes. But when we're home and daddy's working on the laundry or the food, the kids are the kids' responsibility. You're bored? I'm glad! Kids should be bored sometimes. Hungry? Good! Dinner's in an hour. Etc. If you're someone who feels it's very important to entertain your children, this kind of thing can be pretty stressful. Things gradually become much easier as they get older.
Edit: I see that you've already pulled the trigger and have been at it for more than a year. That's amazing. You probably don't need any advice then. But I'll leave this for anyone who finds the thread later.
