Hi Jill2778,
You are asking a very good question. I started life as an Episcopalian (christened as a baby), converted to Catholicism as a young adult, and I began attending a Baptist church 4 years ago. I was baptized two 1/2 years ago as an adult.
In the Baptist church, one is able to participate in the Lord's supper after one is baptized. There is no traditional age for baptism. When one professes the belief in Christ as his/her personal savior, that is when he/she is ready for baptism. This can happen at a very young age or at a very old age (like me, LOL). It is God's Grace through faith that saves the new believer (whether that believer is 5, 10 or 35!)
Baptism itself is NOT salvific. Baptism is a powerful witnessing tool, and it does mean that the baptized person has joined that church community and can be a voting member of that church. It also means that the person can participate in the Lord's supper.
Some churches put pressure on older children to get baptized as though baptism were salvific. It is not.
Sometimes adults choose to get baptized again as a show of real faith (as opposed to the baptism received under pressure as children). Again, baptism itself is NOT salvific, but sometimes adults realize that they really HAVE become believers and they want to get re-baptized as a SHOW of their newfound faith.

Some parents have older children participate in communion just because they are at church. This is considered improper if the children aren't actually believers.
