Can I just ask?

So I have 2 really dumb questions but honestly why I’m asking is because I’ve never taken care of a newborn so I know very little. If you could please help.

1). When you’re out and about how do you warm a bottle up (let’s say you formula feed) Some people I know use warm water in a sink.. but what if you can’t get to a bathroom, microwave, or a bottle warmer?

2). Where in the car should a car seat go. Drivers, middle, or passenger seat?

Ps. I know these are stupid ass questions but I have my first child in 12 days so I’m trying to learn whatever I can.

TIA..
