Leaving baby for the first time 😬

My husband surprised me with monster truck tickets out of town this weekend for our oldest. While I'm super grateful, I'm not ready to leave our 6 week old with my mother in law yet.. I haven't even left the house for anything more than a doctor appointment or grocery pick up since his birth or let anyone hold him. It's 3 hours of driving to get there and back, plus 4 hours or so for the show and I'm sure he'll want to stop somewhere else in between.. That's like 2 or 3 pump sessions in the car. 😫 I'm so not ready.
