When I was about to get married, one of the things my sister-in-law told me was to immediately set up a week night that my husband and I could use as our weekly date night. She said it was so important to get that rhythm established before bringing any other kiddos into the family. As a great listener, I did exactly what she said ..... NOT. I didn't take the advice and I wish I had!
We joked about 3 years ago when the time was coming for us to renew our CPR certification for foster parenting. We HAD to take a day away because we would be decertified if we didn't renew it. It was pretty sad but we had to laugh because that was our first date out in about 5 months. We had three kiddos of close age and going out just never seemed feasible.
Thankfully, Patrick and I (almost 6 years later) are now in a rhythm where every other Monday night we sneak away for time with just us. We have a recurring babysitter who comes every other Monday from 7-9. Whether we walk to the end of the street for ice cream, take a jog up the stairs by our house, or sit on the front porch - it doesn't matter. What matters is that we both prioritized time for one another to be together.
I'm not sure what it is for you but I would encourage you to try it out! Make it once a month in the begining and add on time if possible. If finances are an issue, you can ask a friend to date night swap (who doesn't love watching netflix at someone else's house where you don't have to think about chores!), barter laundry/dinner with a college student, or enjoy a date night in!
