I hate to leave a dirty table when I dine out and it’s especially challenging when dining out with kiddos. I usually take a Ziplock bag with me and as trash piles up, I add it to the bag. At the end of the meal you can throw away the bag or leave it on the table for staff to discard easily. The staff will be happy to see you on your next visit

Regular water bottles for kids with the latest cartoons on them typical aren’t insulated so if they have anything with ice in them they sweat.  I place them in coozies and then write their name on the coozie it stops it from sweating and isn’t cold on their hands  and you can label it even when you can’t write on the bottle because it’s too wet or slick.
