According to the Catholic Catechism, bishops, priests and deacons can perform baptisms. In extraordinary circumstances, however, anyone can perform a baptism. See http://www.usccb.org/catechism/text/pt2sect2.htm#1256
I have to say that I am not an expert, but I do have my opinion. I think that baptism should happen later(instead of infant baptism) because that is when they actually know what the correct choice is.
Infant baptism is practiced in churches, as they say that nobody should be lost.
Yes, "Baptism" should be capitalized when referring to the religious sacrament.
There is no worst time for baptism, but it should occur as soon as the person is ready.
Baptists believe in believer's baptism, which means that individuals should be baptized only after they have made a personal decision to follow Jesus Christ. They do not practice infant baptism, as they believe that baptism should be a conscious choice made by the individual.
Only when referring to the religious sacrament or rite: "Sacrament of Holy Baptism". In referring to the event (e.g. "my child's baptism), it is not.
Baptism should occur only when the party to be baptised is old and wise enough to make an informed decision on whether or not to consent.
It should have the seal of the church stamped onto it; the same church of the baptism record
Common courtesy dictates that you should go to the baptism and then go to the reception. The reception is, in a sense, a 'reward' for being present at the baptism.
Generally speaking, no one should ever be denied baptism in an Orthodox Church, as baptism is necessary for salvation.
That You Remeber your a child of God forever.
If you are enquiring about the baptism of a particular individual you should contact the local Kingdom hall of Jehovah's Witnesses.
