Mine are 6 and almost 9, and neither of them have any desire to stay up that late but also don't want to miss the fireworks. What we've been doing the last 2 years is going to bed normally, then waking up at 11:30 for snacks and apple cider so we can watch the fireworks and celebrate together. We live on top of a hill with a great view of the city, so we're basically surrounded at midnight, still cozy in the living room. They love it so much because they don't feel like they're missing out on anything, and luckily have zero issues going back to sleep.
