With your due date set, it’s time to pack a bag for your stay at the hospital. Pregnancy bags include essential and comfort items for your delivery and postpartum travel. Use our pregnancy bag checklist to make sure you have everything you need for your big day. We also included the average costs of items you may not have at home, so that you can budget accordingly. Start With These Pregnancy And Postpartum Essentials Your pregnancy bag should be packed by week 36 in case you go into labor early. Even if you already own a few items on this checklist, you may not have time to pack them right after your water breaks. With that in mind, consider buying an extra pair of leggings or toothbrush to pack in your pregnancy bag, so that you aren’t rushing to bring it all together at the very last minute.
