New study: most babies are smaller than doctors predict

A new study (summarized here: http://nyti.ms/1N5khZE) has shown that we are more often than not wrong when it comes to estimating that babies are going to be large. This matters in a big way if the reason your doctor or midwife is recommending a C-section is because they think your baby is too big to deliver vaginally. While there are definitely some instances where recommending delivery by C-section (more here: http://nyti.ms/1N5khZE) is appropriate, you should always confirm that your obstetric provider is using the right cut-off guidelines for what we think makes a vaginal delivery dangerous. Otherwise you may be ending up with an unnecessary C-section, which is a major surgery that should only be used when absolutely needed!

  1. My OB/GYN guessed my second baby’s weight to the ounce… But my first OB/GYN was a pound off with my first. Interesting that doctors would use their guesstimates to push C-sections when they are often wrong.

  2. I think this is so interesting because anecdotally, I have found this to be true on occasion. Of course, it depends on the doctor and is not generalizable to all OB’s. As a physician, I also empathize with the OB’s desires to get the baby out as safely as possible.

    1. True. And I’m sure many times there are other risk factors for the moms that are coupled with the weight estimate that put the C-section conversation on the table.
