I (27M) am wondering how financials should go with my soon to be SAHM wife (27F)

So for starters, my wife is amazing, I love her to death, she completes me. However, she is TERRIBLE with money. Her father finally had to pay her medical bills because her paychecks were getting garnished, she has never been able to pay bills. She was a hairdresser and never put her 30% to the side for taxes for the year and I had to buy all of her equipment, pay her taxes, etc, sometimes even her booth rent.

And through all of this, she has made money. She’s never been able to save a single $ even when I offered to pay all bills and gas so she could save.

So recently her and I agreed she should quit her job because at this point I was paying money for her to work with nothing to show for it and we have a baby on the way.

She’s been asking about getting an allowance. The thing is, I don’t want to feel like I’m controlling finances but I think it’s a bit weird to give my wife an “allowance”, but I’m also terrified of giving her access to big quantities of money. We recently moved into and renovated a house and we have NO savings in prep for baby.

I’m reaching out to get some input from other SAHM’s and figure out how to navigate this situation. My wife would never deplete us to absolute zero and she’s by no means rude or bitchy about money. She just literally cannot comprehend saving and not going to Home Goods or Marshall’s 4x a week.
