How did your marriage change after twins?

27 weeks now, expecting fraternal boys soon. We already have a 3 year old. Our first pregnancy / birth really rocked our marriage and I feel like we finally rebuilt from the ashes. And now unexpected twins. I’m so nervous.

We’re both prone to depression. Often the mental and household loads don’t feel balanced. We’re hiring a night nanny for the first couple months but don’t have much family or friend support otherwise.

Any advice? What have your experiences been?
