1. Stop trying to go to the nicest and hippest and newest places
I'm not saying you shouldn't go to these places generally to enjoy their hot new takes on dandelion greens and kohlrabi. I'm just saying that you might want to reserve these types of spots for nights out with a babysitter. New, hip places tend to be crowded and unfriendly to the kid element, and nice places should just be off the list, because frankly, no one who comes to a nice, expensive place, possibly for a special occasion, deserves to also bear witness to your child spitting the amuse-bouche onto their oyster fork.
You should still be able to pick good, cool spots, but, you know, maybe the ones that have been around for a little bit and might give you a little more space and cut you more slack and don't serve amuse-bouches.
2. Just go early and deal with it
Yes, this advice may seem obvious, but there have been several recent occasions when I've been out to dinner sans children at 9:30pm and seen toddlers absolutely dragging and losing their shit while their parents are still cranking on the cabernet. And maybe that is a French thing, and you're not supposed to let your kid dictate your schedule, but I also recognize that when children sleeps a regular amount of time, they are tiny angel people, and when they sleep an irregular amount of time, they are all basically tiny Cersei Lannisters.
Plus, whenever we show up to a restaurant with our child and it's 5pm or like 9am on the weekend and I see some other non-children'd people in there, I mentally am like, "OK, other people. By agreeing to come this early to a restaurant, you have basically already signed a release stating that you are OK with children and will not sigh audibly when my daughter inevitably starts shouting every noun she knows."
