Because not everything that happened in the first 30 years of the church are recorded in the New Testament.
Consider federal headship; and the covenant. how Jews thought in regards to their children, based on that covenant. For thousands of years, the nation of Israel saw their seed as instrumental to God's plan of redemption; then, the NT comes along and all of a sudden, the Jews are to think differently? Their seeds are not included any longer, in fact, they are, by default, outside the camp. This notion would be classical if in fact, this were true. But, since we see no indications that the children are now 'outside', this is exactly why we see no conversions of children at all in NT writings because they were already under the covenant.
