Anonymous asked: Is it physically possible for a body to make a baby that is too big to deliver vaginally? I was born via C-section after mom pushed for hours, and from my understanding it was because my head was simply too big to fit through the birth canal. I wasn't an exceptionally large baby weight-wise (8ish lbs), but apparently my head was too big. Maybe there were some other circumstances that lead to my mom's C-section, but I'm just wondering if a baby's head size can NECESSITATE a C-section?
Well yes and no. Mostly no, but a little yes.
See, in a healthy pregnancy it is impossible to grow a baby that is too big to get out. It just doesn’t happen. Not only do babies just not grow that big, but we are designed to make that not happen. Babies’ skulls are not finished forming when they’re born (remember all that bit about the soft spot?) because the point is that the bones can squish together during labor to fit out through the birth canal.
This is what is normal and expected and fine to happen during birth:
It all goes back to normal after birth.
Also, there is a rise in a hormone called relaxin during pregnancy - it loosens the joints and cartilage and tendons and even makes the bones themselves more elastic during pregnancy and birth in the pregnant person.
See how there’s more space in the pregnant one there?
So these are all the reasons why NO, there is no such thing as a baby too big to fit out of the pelvis/birth canal.
But then there are the very rare, unlikely instances when it can happen:
- A baby born to a parent with pre-existing or gestational diabetes can grow exponentially during pregnancy, making it too big, or at least too big of a risk to even try giving birth vaginally. This is a soft call, but babies born to gestational diabetics have a much higher risk of shoulder dystocia (getting stuck at the shoulders), so many providers have a lower threshold for deciding to move to c-section with these patients.
- If the parent had been in an accident of some sort and broken their pelvis, which healed in a way that was in compatible with birth - too narrow or too long, etc
- If the parent had a pelvis of a very uncommon but naturally occurring shape that did not allow for vaginal birth. In the image below I crossed out the pelvis shapes that are much less compatible with vaginal birth, but remember that anything is possible, so if I had a patient who wanted a vaginal birth I would never tell them they had to have a c-section, even if they had one of these shapes. We’d try labor first, and do everything we could, until it became clear that it would not happen.
Then there is the issue of baby’s position. Even in a pelvis that is the right shape and with a baby that is the right weight, if for some unknown reason that baby gets settled down into the pelvis in the wrong position, it can make labor either extremely hard and painful, or make vaginal birth impossible.
See, in the image below they measure the widest part that would have to fit through the pelvis depending on position:
So if a baby comes back-of-the-head first, like in A, they’re in good shape. If they come face first, like in D, usually they’re OK, but it can be pretty difficult. If they come in top-of-the-head first, like in B, it can be very difficult/impossible, and if they come in forehead first, like in C, they usually just don’t fit. (Remember - none of these are absolutes. I’m just talking about the most common scenarios.)
Then there’s what angle the baby hits the pelvis at - is the baby’s face towards the parent’s spine? Towards the parent’s belly button? To the side? All of these affect it too.
So, back to your question. It is possible that you were in a position that just wouldn’t let you out of the pelvis - this happens. Or it’s possible that your mom’s doctors just got tired and decided to call a c-section. Or even though you would have eventually fit, you got too tired and your heartrate started dipping, making it so that they were nervous to keep trying. There are many reasons. But know that in almost all situations, babies fit through their parents’ pelvises.
