The beginning of Shabbat is a particularly appropriate time to bless the children. It is customary to bless children of all ages, either in the synagogue after services or on returning home before Kiddush. Both hands are laid on the head of the child to symbolize a blessing imparted with complete generosity of spirit.

For a boy: May G-d make you like Efraim and Menashe.

For a girl: May G-d make you like Sarah, Rivka, Rachel, and Leah.

For both: May Hashem bless you and protect you. May Hashem cause His face to shine upon you and be gracious to you. May Hashem raise His face to you and establish peace for you.
