The baptism of the jailer at Philippi: St. Paul and St. Silas said to him: "Believe on the Lord Jesus Christ, and you will be saved, you and your household" (Acts 16: 31), This means that the jailer's belief would be the first step which would lead his household to salvation. That is why it is said after that: "Then they spoke the word of the Lord to him and to all who were in his house" and then "immediately he and all his family were baptised" (Acts 16:32,33). The Holy Bible did not exempt little children from the household of the jailer at Philippi but said about their baptisms: "...he and all his family”, of course including little children.
