We used this prayer on Sunday at our Children's Sabbath. All the children moved to the center aisle, and the people raised their hands in blessing, and said:
Guard the laughter of children.
Bring them safely through injury and illness,
so that they may live
the promises you give.
Do not let us be so preoccupied with our purposes
that we fail to hear their voices,
or pay attention to their special vision of the truth;
but keep us with them,
ready to listen and to love,
even as in Jesus Christ you have loved us,
your grown-up, wayward children.
I believe that this prayer is from the Book of Common Prayer
