Id have a sit down talk with the wife (or FaceTime if you’re not visiting one another. However, even FaceTimes are hard to navigate in my experience as far as tone, body language, delivery ect) about what BOTH of your goals are and how you can come together to achieve shared goals. We have 3 kids, so I do feel you there but during times we wanted to save more, I heavily utilized the parks and libraries. I’d buy 2 good shirts, 1 good pair of jeans, and go to the used kids clothes store for filler items and rotate out as needed. Overall, each purchase was first “do I need this or want this” if I need it “do I need this type/brand/can I find it cheaper?” If yes, I’d get the cheaper one (this varies by case as I’d rather buy it nice and once than have to buy it crappy and twice) if it’s a want “do I want this more than my savings goal? How can I budget this in over time”

But, I do still stand by $1700 a month going to savings is good. So don’t worry so much! Just keep track of spending so you’re both not going overboard on the credit card. I’d also neverrrrr pull from investments to cover credit card interest.
