Parents who bring their children for baptism promise to bring them up as Christians. This is a serious commitment.
If you haven’t practised your religion for a while, now that you have a new baby it is a good time to find someone you can trust to talk to about your faith.
Most priests are only too happy to welcome you and give you time to talk things through. A friend who goes to church might also be willing to help you sort things out.
Some parishes have a group that helps with the preparation for infant baptism. You need someone who will honestly help you with your doubts and questions.
Better not to rush. Your child’s baptism will mean more to you if you have a living faith.
