What else do we need to prepare for if husband stays home?

We've run the financials (budget/expenses, retirement, health/life insurance) and everything checks out for my husband to stay home with our little one. And we plan to have another in the coming year or two.

​

It's what he has always wanted, and I want it too. He's an excellent father. I think I can handle the pressure of being the financial provider for our family but we've talked through sacrifices and scenarios if either of us aren't happy with our 'new roles' and how we'd handle it. A worry for me is mental load (I'm the planner of the house right now).

​

What are we not thinking of? What do you wish you'd figured out before you decided to have one parent at home?
