Carseat? Hospital bags? Help!

Mary • 20 years old, engaged, mommy to a babygirl born on July 22nd, fur momma to my Yorkie-Poo, Zelda :)

I am almost 34 weeks pregnant. It has been a healthy pregnancy this far, although I went into L&D for cramps and spotting 2 weeks ago but everything turned out to be fine.

My questions are, When should I install the baby's carseat in my car?

When should I get our hospital bags together?

Also, any advice on things to bring in the baby's bag/husband's/my bag that I might need.
