Pajamas or loungewear and going home outfit for baby. Hospital provides a loooot of things for me- toothbrush, shampoo, pads, mesh underwear.

Do it early. I packed a random bag at 26 weeks and was happy I did because I had to spend a night in the hospital for contractions at 28 weeks. So when I got home, I packed another bag and look at me now at the hospital on bed rest till the babies come!

Whenever you feel like it really. Some pack in the last couple week of their 20's others wait till 30's and even some wait till last minute. I finally just got mine packed two days ago and I'm almost 36 weeks lol
