Is a breech presentation considered a labor complication?

Play on words. You could consider it a challenge or a complication depending on the setting. If baby was head down all of pregnancy & came in for delivery as breech, i'd consider it a complicating factor to what may have been a simpler delivery. Since the head is the largest body part to deliver, bottom out kids can get stuck so C-section is often necessary but a surprise. Breech deliveries are more of a challange.
