Leaving child over night

Okay! So I have a 16month old. I have left her overnight 2 nights for a trial from 8pm-8am. I was only 5 miles away and went to get her the first thing in AM. In a couple weeks I am leaving her for 2 nights and we will be 300 miles apart. She will be staying with my mom, but I'm still SO SO SO not ready for this! Please tell me your words of encouragement! 😑 I might just end up bringing her to the wedding! But I know it'll be ok and good time away from her too. UGH! I'm torn. I'm contemplated staying home too, but SO is in the wedding and bride is a friend...
