Not everyone wants the same person to deliver all of their children, or they might not think that having a relationship with the person delivering your baby is absolutely necessary – its not. However, your labor and delivery might go more smoothly if you do. You have to trust the person that you're putting your and your baby's life in. This is due to the fact that they have to know exactly what needs to be done, when, and why and if they do not then you're not going to feel very comfortable when the time comes to deliver your baby.
Choosing a midwife not only can empower you when the time comes to give birth, but it also means that you have found someone that is there for you 100%. They are more personable and understand everything that you're going through. They know that labor and delivery can be tough and they are there to see you through it every step of the way. Without this, they are not going to be able to create a relationship with you. They will come in to check on you and catch the baby but after that point in time, it is done and nothing more is said on the matter. You should keep this in mind if you want someone to talk you through, make you feel good about the progress that you have made or just come in and check or catch and walk out without words.
The choice is ultimately yours since it is your body and your baby, but many people state that midwives empower them to keep going and to stick with their birth plans. If this is something that you want then it might be time to move forward and talk with a midwife. They will be able to give you a better idea of how things work and what they can do for you and your little one to make the transition as easy as possible.
