The first five years, understood.

One class for each window of the first five years. You learn the mechanism, the evidence, and the limits of what anyone can know about one child, at your own pace.

Clear about what’s known. Honest about what’s not.

$49 once per class, or all three for $119. Lifetime access, no subscription. Full refund within 14 days if you have watched four lessons or fewer. Matthew writes every lesson; the narration is an AI model of his own voice.

Fig. 1Each class covers one window of the same childhood. The family class applies at any age.
