Planning 1st kid stay during 2nd labor

I’m 3 months pregnant with my 2nd. My first will be Nearly 3 when this baby is due. My first birth was so fast and unpredictable. My water broke 5 weeks early and I had to rush to the hospital (which is 25 mins from my house).

We’re obviously hoping to avoid going early this time but I’m concerned on what to do if it happens again suddenly like that. If this happened to you and you already had a child, did you just rush them somewhere really fast? Lol

Also, if it was the opposite and your labor was long, how did you plan a stay for your other child?

Any advice is appreciated 🙂
