Lol at my childbirth class they said you can honestly pack anything that will help you to be comfortable as long as it's not too big so go for it haha @gionna_sav
I didn't know what to pack either but my bag is ready now, I packed 2 nightgowns, a robe, slippers, underwear, 2 nursing bras, going home outfit, and toiletries. hope that helped :)
