Ideally, you should convince your spouse of it, to go rent together. Maybe try couples therapy together, who can help you navigate your discussion as a family. Yes, it’s good to save money and to have a downpayment. But if it’s sacrificing your mental health, that’s not a good choice. It’s much better to rent for an extra year or two and enjoy time with your new family additions. Rather than “buck up” when it’s already too hard during and at such an important period of your life with the new arrival.
