It is Jewish custom to bless children each Shabbat and on every festival holiday. The customary blessing that parents bestow on their children on Shabbat and holidays is specific to boys and girls. The blessing offered here is appropriate for people of all genders, including nonbinary genders.
You may choose to place your hands on the child’s head, shoulders, or back, as you recite the words of blessing.
יְהִי רָצוֹן שֶׁשַּׁבָּת זוֹ תַּשְׁרֶה (שֶׁחַג זֶה יַשְׁרֶה) עָלֵינוּ אוֹרָה, שִׂמְחָה, וְשָׁלוֹם.
May this Shabbat [holiday] bring us light, joy, and peace.
Some may add this additional blessing:
Be who you are –
and may you be blessed
in all that you are.*
