Hello girls. I'm packing my things for the hospital and can't figure out how many bags I need to take with me? Three at once? Or can I go with just one bag to the hospital? I bought a bag for the maternity ward in a set: one big one, one medium one, and one like a cosmetic bag. I'm going to the hospital for the first time and don't quite understand how to do it best. Can you please tell me? And about after the delivery room. Can you please tell me will the baby be with me or under the doctor's watch? Thanks in advance for your answers.
