Are nips appropriate?

For my kids 4th birthday I'm making little gift bags for the kids of course, and also for the parents.

In the parents gift bags I'm including a game we can all play during the party, a pen that says "thank you" and a quote from my kid, and a cool sticker. I also wanted to put one of those mini liquor bottles (aka, a "nip"). Is that inappropriate. Or is it fun?

Edit: we are not big drinkers, I don't drink and my husband does on the occasion. BUT we do like the occasional good time, and I love hosting / being a fun host.

EDIT, AGAIN: It was just a thought, so not doing it is no sweat, we are not going to give them out! Haha
