At Christmas, when Henry was two months old, we booked tickets to see Once on March 6, a week after he turned four months. I was sure that he would be sleeping without problems at night (he isn’t), and that I would be ready to leave him (I wasn’t). But, the tickets were booked and we were doing it. My parents were the designated babysitters, and I left them (a modest) two index cards of instructions, and only ran them through the whole bedtime routine once, and resisted the urge to quiz them on it.
We went for a really nice dinner and then out to the show. We did kill some time before our reservation in Indigo, and bought Henry some new books, but otherwise tried to focus on just enjoying the time to ourselves.
