Making your child’s room into a Mikdash Me’at:[1]
Even today, every Jew is obligated to make for himself a dwelling place for G-d within his home. This obligation is relevant even for children, and even for a newborn baby. It can be accomplished by placing inside the babies room a book of Chumash, a Siddur, a Hagadah of Pesach, a Sefer Tehillim, and a charity box. These books should be personally purchased on behalf of the child and be considered as his. To sanctify the room, one should try to study some amount daily from the child’s Chumash, and to pray or say blessing from the child’s Siddur, and to give charity in his charity box.
Filling a Child’s Room With Sifrei Kodesh[2]
The Rebbe emphasized the importance of having Sifrei Kodesh in a child’s room. The very presence of holy books leaves a powerful impression on a child and helps create an atmosphere of Torah and holiness. However, the intention is not merely to place a single sefer in the room in order to fulfill an obligation, nor only to have a siddur that the child uses for prayer. Rather, the room should be filled with seforim, reflecting the ideal of a Jewish home that is centered around Torah. Just as it has often been stressed regarding adults that a home should be “full of books,” demonstrating that Torah is the central focus of the household, so too a child’s room should visibly convey that Torah occupies a primary place in his life. Everything in the room should support a Torah way of life and be used in accordance with Torah values. The Rebbe therefore recommended that every child’s room contain at least three basic seforim: a Chumash, a Siddur, and a Haggadah. It is also highly desirable to add a Sefer Tehillim, whether as a separate volume or as part of a siddur in which Tehillim has its own distinct section, thereby emphasizing its status as an independent sefer among the holy writings.
