It is always lovely to welcome new members into the family of the Church. Everyone wants to give thanks for this new life! Often, when parents bring their new baby to the service for the first time, they take it to the front and then walk down the aisle so everyone can see.
Sometimes parents choose to have a service of Thanksgiving and Blessing rather than a service of Infant Baptism. They want to give thanks for their child and ask for God to bless him/her. The vicar takes the baby in his arms and prays.
