In the Baha'i faith there are many beautiful prayers for children.
Here is one example;
OGod! Educate these children. These children are the plants of Thine orchard, the flowers of Thy meadow, the roses of Thy garden. Let Thy rain fall upon them; let the Sun of Reality shine upon them with Thy love. Let Thy breeze refresh them in order that they may be trained, grow and develop, and appear in the utmost beauty. Thou art the Giver. Thou art the Compassionate.
