These are a non-religious alternative to ceremonies such as a christening. During the ceremony, you as parents, state your love and commitment to your child and declare your hopes and dreams for their future. It is a lovely opportunity to welcome the baby into your family and friendship circle. You may want to appoint guardians (alternative to God Parents). Perhaps you have a favourite childhood poem that you would like to read or a favourite piece of music?
Although as a Celebrant, I offer a non-religious alternative, if you would like a prayer to be said or a hymn to be sung, I would be very happy to incorporate it.
This sort of ceremony may be appropriate for new babies; adopted children or welcoming two single parents children into the family.
