What ever birth you have planned whether a hospital birth, going into a birthing unit or having your baby at home its good to have a bag (or bags!) packed in case you need to go in to hospital.
Obviously you don’t wan to have so much to take with you it takes four trips from the car park to the birthing suit this will not add to a calm vibe!!
You can leave some stuff in the car until after birth and when your partner is ready to get the car seat etc.
