3x moms, where are your older two staying when you head out to the hospital?

What's your plan for where your older kids are staying? How are you arranging in case of a sudden need to go to the hospital? I'm due in 4 weeks and am so nervous more so of where my older two will go if it's sudden and before due date. Hospital is 8 min away from my house but closest family is at least 30 minutes away and husband works an hour away. I have my hospital bag as well as their own bags for when the day comes.
