This is a somewhat touchy subject also (aren't they all )And then I'd gotten into infant sprinkling. or tried to.
Yes infant baptism is something the RCC does, and then later when you are older (usually in mid teens or so) they have something called confirmation.
However... this is where it's starts getting tricky into "what is a Protestant". I said earlier some churches that consider themselves to "Protestants"
still follow many RCC and "eastern church" practices. Are they really Protestants... I don't know. But they have priests, cardinals, archbishops... and infant
baptisms and confirmation. So to these people (typically Episcopalian/Anglican and Lutheran ELCA) this an accepted practice... "because we do it my church".
I suspect this is why you have not gotten many replies on this.
Most "mainstream" Protestants, do not support this. However they believe in something called "infant dedication". It is not a baptism at all.
Merely a promise from the parents to the church, that they will raise the child as "Christianly as possible" and the church agrees to help them in this "as much as possible".
The child makes their own decision to get baptized (or not) when they are old enough to be responsible for their own decisions.
Now... that I have offended not only RCC people, I hope this thread keeps going.
