Welcome to the club, GrandMA. Get "your" bag packed. Take a tooth brush, makeup if you wear it, a change of undies and maybe a clean shirt. Also a book, magazine and/or sewing AND your laptop if you have one. You can leave all this in the car but SOOOO nice to have because..........
I had to travel 1 1/2 hours when my daughter had her baby and she was in labor for 18 hours. I didn't want to leave. SOOOOO glad I packed my bag.
Blessings. Keep us posted
