I give to each member of the congregation a cut-out footprint, and as part of the prayers, invite them to write on it a prayer, or word for the child/baby being baptised.
This could be simply something like, ‘friendship’, ‘Love’, ‘happiness’ or an actual sentence of prayer. Younger children might like to draw a picture.
The footprints are then collected together and threaded onto ribbon to create a book. The front footprint could have the child’s name, and date and place of baptism. This is then given to the family at the end of the service.
My families have loved doing this, and have enjoyed reading what others have written for their child.
