I Believe Children Who Get Saved Should Be Baptized Immediately

I have heard of some groups that have actually prevented younger members of their local New Testament churches from getting baptized unless they are adults or teenagers. That is nowhere in the Bible? Do you know what the Bible requires before the sacrament for baptism is administered? It's all about believing first before you can be baptized. You don't get saved by participating in the sacraments nor stay saved by them. You participate in the Christian sacraments because you're already saved.
Acts 2:41 
Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls.

If a child has received Jesus Christ as one's Lord and Savior then why do we hinder them from baptism? Baptism is a command that's already given for those who are saved (Acts 2:38). First they believed and they were baptized. If a child gets saved then why let one's age be a hindrance from being baptized? There's no specific age for a believer to receive baptism. Have you repented of your sins and received Jesus as your Lord and Savior? Then you're in. Are you below 13? You're not exempted from the sacrament. 

That means when the child understands and accepts the truth that one's a sinner and Christ's the Savior, that they are sinners and God is holy and receives Jesus as one's Lord and Savior - then by all means let them have the sacrament of baptism. Then there's no need for first communion since all saved members regardless of age may automatically participate in the sacrament of the Lord's supper.
