It is quite natural to be excited as well as nervous to experience this next step in their journey of faith. Some children become more nervous than others. If you feel your child is a bit more anxious, consider having your child write on the back of their “My First Confessions Printable” (or any paper) what they plan to say to the priest. They can take this paper with them when they receive their sacrament to help them feel more confident.
As a reminder, adults are welcome to wait with them in the pew and to help calm their nerves as you feel they need that extra support until it is actually their turn, however, they will then need to complete the sacrament on their own.
When the sacrament of Reconciliation is offered to minors, parents and other adults should be able to see their child (through glass or distance) without overhearing the conversation. This follows basic safe environment protocol.
