What does it say in 'YOUR' bible? Read Mark 16: 16.Whoever believes and is baptised will be saved; whoever does not believe will be condemned.
This could not be clearer regarding the most important instruction we have been given on the subject.
Q: When you read the bible and come to understand and believe, then you are ready for baptism. This is a very personal thing, you cannot do this on behalf of someone else.
It is always a good idea when perplexed to ask the question; "what would Jesus do/say?
Jesus was baptised when he was 30, he had gained knowledge and understanding.
Q: How much knowledge and understanding does an infant have?
As a baptised parent your baptism covers your children while they are young. You guide your infant to the God of the bible until he/she is an understanding adult, then they get baptised as the scripture says and as Jesus did.
