What mainstream sects object to infant baptism?

I recently had an interesting discussion with a person who did piercing for a living at one point in time in his life. He told me that the shop he worked had a policy where the would not pierce a baby's ears. To him it was an issue of ethics. He told me that the shop he worked for would only pierce a girl's ears if she was at least 5 years of age and only if the child / girl specifically asked for it herself. I have done some soul searching and I have come to realise that this issue of ethics has come to encompass my views on infant baptism as well. I don't believe that any person has the right to choose to have another baptised. It is to me a deeply personal decision that everyone must come to ass they become of age. Ultimately I would like to share what religious beliefs I may have with my children, but I must give them the chance to become Richard Dawkins, junior if that is what they want to become (Even if that would to happen it would grieve me.) I'm just wondering what kind of denomination holds these beliefs or a reasonable facsimile thereof. My upbringing was entirely secular so I'm completely ignorant on how a person would choose a church. This issue is important to me, if I do ever get the chance to have a child.
