My DD also had to have vacc cause i was tired and also cause her head got a bit stuck. I was advised to have a c/s next time. But i went with my gut feeling and birthed my baby boy with no problems. i also had a epidural with him and he came out really quick.

Were you laying on the bed? That could have been one of the causes. It's definatly not your fault. it's just something that happens sometimes. I advice that next time you try squating or similar so your pelvis is wider for bub's head.
