From the time of the child’s birth, it is incumbent upon the parents to ensure that he is surrounded by holiness. Doing so increases the chances of success in raising him to a life of Torah and the performance of good deeds. Each year on the child’s birthday, the parents should reflect on the fact that they have merited tremendously; God has deposited with them a soul inside a body. They should consider the way to educate the child so that he will walk a straight path.

One should see to it that from the time of birth the child is surrounded by holiness:

Another crucial matter with regard to the newborn is that after he comes into the world he should immediately be surrounded by holy matters. It is known that the things that an infant, even one who is one day old, sees and hears have an impact on his development (recently, modern psychology has adopted this age-old insight). Therefore, the infant’s being surrounded with holiness brings blessing and success for [his parents] to merit raising him or her to [a life that includes] Torah, marriage, and good deeds.

The merit and joy of raising and educating children:

The main thing [for parents] is to reflect on the greatness of the merit and joy that have come to them because the Holy One, blessed be He, deposited into their hands a soul in a holy body, relying upon them to properly safeguard this precious security by educating and guiding the child in the path that leads up to the House of God.
