Churches who baptize kids are usually 'Nicolatian' in nature, attempting to conquer as large a congregation as they can, not disappointing anyone, but filling their churches with all manner of unsound people to gain and expand. So they will grab a child as soon as they can, else they could loose it to another church. This surely is not the work of Christ and the Holy Gospel.
The other thing those churches dear to do is to not actually Baptize ( push under water then pull back out of the water ) but, mainly in Catholic churches, they even go as far as to pour a cup of water over your scull which they then gather in a bowl as it flows down. How deceitful and arrogant: how brutal! And why this? Because, as you can imagine, or you may have seen, it is a huge problem to movanage large volumes of water in the churches, and also to discard of the used water is a problem. Properly build churches have Baptism pools built-in, as it should be. Or, indeed, they should go and find a river or a loch to perform the act. But certainly, they should not make things easy for them selves by 'corrupting the Baptism' as the Roman Catholic and other Catholic Churches do.
Those who join a church under false pretence, for whatever reason other than to join the church in the name of Christ, are baptized into that church, not into the Church of Christ.
Note that, if your church organization is not a Church of Christ, but pretends to be: as you walk into the Baptism earnestly, you will be baptized; even if a rogue minister/priest baptizes you, as you have surrender to Christ that and you knew not of this evil.
People best do not baptize before marriage; and if they devorce they must devoutly follow the commandments on fornication, all the time, or (not and) remain celibate until they marry again. The wise will surely consider their ways on this subject and exercise caution in case they do sin against God in fornication. To consciously sin and defile your Baptism is highly undesirable: HEB: 10.26.
Christians must understand that from the moment they become Christian they are members of 'The Church' which is not tangible, like the building here or the place there, but is the Assembly of True Christians who walk in the 12 commandments and the doctrine of Christ.
