i dont remmber but i think it is better to get babtized when you are older because you actuelly know what is going on.
Yeah, baptism is like removing the sins you did without knowing the faith, so in one way it's better to get baptized as an adult, but also being born into the faith and growing up with it has a very positive effect on you.
I don't remember if Jesus wa baptized as a baby but I do remember John baptizing him when the dove came down (holy spirit) God was talking about that it was his son and that he was proud of him and Jesus was there. That was teh only time I can remember the bible talking about them at one place except for the creation.
