Best time to pack baby bag?

Shampree • Mom of 1 daughter and 1 son! Angel mommy of 1 💙
I'll be 34weeks tmrw and while organizing baby boy's clothes, i started putting together what i would like to bring to the hospital. When is a good time to prepare the hospital bag? And should i put NB and 0-3M clothes? With my daughter i waited until the day i went in labor and started putting things in a bag and brought her 2outfits and 2outfits for myself. Just trying to be more prepared this time around
