What do my fellow FTM/D have planned for New Year’s Eve?

Before having our little guy we used to go out or stay in and smoke a cigar to welcome the new year( depending on what country we were in). I stopped smoking when I found out I was pregnant so that’s no longer an option but I’m thinking of going to a friends house party yet I have no clue what ppl do with their children at parties. Do you put them in a separate room and let them try to sleep? Do you go for a few hours then go back home when it’s sleeping time? Do you just get a nanny? How long do you let a stranger watch your child before panic kicks in? Do nannies even work on New Year’s eve?

Also we the only couple with a child so my friends are also clueless about the protocol.
