One of the arguments for circumcising day old newborns without anesthesia is that their brains aren't developed enough to feel pain. There was really no research done until now.
Dr. Rebeccah Slater, of Oxford's Department of Pediatrics, scanned the brains of ten healthy infants aged between one and six days old, and compared them to the brains of ten adults aged 23 to 36 years.
MRI scans were taken of the babies’ brains as they were poked on the bottom of their feet with a special retracting rod creating a sensation like being poked with a pencil – mild enough that it did not wake them up.
The researchers found that 18 of the 20 pain regions in adults’ brains also "lit up" in babies’ brains. Scans also showed that babies’ brains had the same response to a weak poke a as adults did to a stimulus four times as strong - suggesting their pain thresholds are lower.
When they wheeled me in for my c-section the surgeon asked if I wanted to have Grayson circumcised. I said that if anyone went near my son's penis it was on. Everyone in the room laughed and my surgeon shared that he hates doing the procedure and he himself wasn't circumcised. It was like a tension lifted.
I couldn't imagine enduring a 20 minutes surgery without pain medication. If only we respected our children and the integrity of their bodies more than our religious affiliation, we'd all be happier.
