Im gonna do mine about 34 works :) im 31 now.
I'm 33 weeks today and decided that after my baby shower, which is next Sunday, I'm going to pack my hospital bag. I'll be 34 weeks then. The reason I am packing so soon is because four of my friends had their babies three weeks early and I don't want to have to worry if I happen to go early.
I think around 38 wks I had the bag with the video camera ready. Along with being sure my camera was charged and SD card clear. I don't think I had a bag packed til after my due date. But I was not dilated or thinning out.
I'm about a week a head of you and I packed my bag last week, but then I unpacked it lol. I'm not due until may 9th. I'll probably pack mine again here next week just in case little Charlotte decides she wants to come a little early. I have all the stuff in a pile in the closet, just not in the bag lol. I like to get things out of the way so I don't have to worry about it later. But it's up to you whenever you want to pack it :)
Idk my daughter has her bags packed & she is only 28 weeks. Lol its already in the car:)
