The Reason Milah is on the Eighth Day

The Reason Milah is on the Eighth Day:

The Meforshim discuss why Hashem commanded the mitzvah of milah to be performed on the eighth day of life, when the baby has no intelligence and cannot have proper intentions, rather than waiting until it is capable of doing the mitzvah on its own. The Rambam (Moreh Nevuchim) explains that the Torah is concerned about the father. The more a son grows, the closer he becomes to his father and the more the father loves the child. Therefore, it is easier on the parents for the bris to be performed when the child is still a baby and their love for him is not yet as strong.
