Interestingly enough, Vitamin K levels (Vitamin K along with calcium is needed to convert prothrombin to its derivative thrombin, which is the enzyme that is the final catalyst to blood clotting) spike to 110% (the highest they will ever be in a lifetime) 8 days after birth, precisely when God told Abraham to have a baby circumcised. Funny how that whole God/science dynamic works...
It is best to have it done at birth.

The law was circumcise a boy child 8 days after birth. Christians are not under the old law, we have a new covenant through Jesus Christ. The Apostle Paul had a whole lot to say about circumcision, explaining why it was no longer necessary.
If we were still under Mosiac law, I suspect we’d have to build battlements on our roof tops, to prevent any guests from falling off our roofs. That’s a law too.
If you’re Jewish, you are still under the law.
