I'm so torn...

We've left LO a few times with my parents for a date night, but never been away from him for more than a few hours. I bought concert tickets in September for my birthday, and was thinking it could be fun to stay in a hotel downtown that night with my husband for a mini getaway. I'd take my son to my parents for the night and pick him up the next day. It sounded like a great idea to me at first, like 3 hours ago, but now I feel sick about it and am thinking of everything that could possibly go wrong and how I don't trust them. I mean they're my parents and they raised four kids, but he's my baby 😭😢😭😢

What do you think? Is this just normal anxiety and I should take a chance on a night away? Or should I call it "mother's intuition" and stay with him?
