How do you do anything when LO has an early bedtime ??

We moved our LOs bedtime up to 6:30 recently and she is sleeping SOOOO much better but it’s impossible go to dinner anymore or over to family/friends house 😩. We have an Memorial Day party that we are debating on even going to cause we would have to leave shortly after arriving.

Obviously we could just stay out later but the one time we did miss her bedtime she had a VERY rough night and terrible whole next day.

So this question is just for those who are adamant on keeping LOs to a routine and an early bedtime. Do you just completely stop doing anything lol.. or get a babysitter every time or how do you do anything ??!! Lol ugh we are going stir crazy. 🙈
