What gets packed in the hospital bag may vary depending on your various preferences. Customize your own packing checklist using this comprehensive list to guide you. It would also be wise to check with your hospital to see what supplies they offer to birthing parents.
For convenience, you may want to pack two bags, one bag that you carry in with you for labor and another bag that waits in the car until after childbirth. You may want to reduce the amount of "clutter" in your birthing room and simply stick with the essentials for this momentous part of delivery.
To make sure that you have everything you need and to help make the task easier, partners should pack the bags together well before the estimated due date. Mothers who have had preterm labor or are considered to be at high risk for early delivery, bags can be packed at 32 weeks or earlier if necessary. Most expectant mothers prepare their bags at 36 weeks.
It may be helpful to organize the items on a large table or bed before placing in the bags. This will help you both do a final quick scan of your packing list. For last minute items, keep a short list of items that will be needed to "grab and go" right before you head out the door.
