Being baptized is a public expression of faith. Although many denominations practice infant baptisms, my belief is that these are more in line with being a Baby Dedication, because all examples of baptisms in the Bible [that I'm aware of] include someone coming by choice, following the instructions to repent, and be baptized.
If you are old enough to understand salvation and the consequences of sin, you are old enough to receive the gift of salvation and give testimony to that fact by baptism.
