I'm sure everyone else has put forward some extremely good arguments, so I won't say too much.

Personally I would never have a son circumsised. I've read studies that have said the reason the baby sometimes doesn't even cry during the procedure is because they are in so much pain their body goes into something similar to shock. I was at the birth of my best friends baby and saw how much he screamed after his hep injection an hour after birth. If that tiny jab hurt, I can't imagine what having your penis skin cut up would feel like.

Also, I watched a video that showed how the procedure is done in newborns and I thought it was horrific. If you don't want it done but your DH and his family are still wanting it, my suggestion would be to have them watch a video on how it's done. I'm pretty sure you'd be able to find one on youtube or if you googled it.

Good luck with everything!!!
