During the communist regime in Romania there was a ban on abortion and the state encouraged people to have lots of kids (sound familiar?). This lead to A LOT of kids in orphanages and not enough resources to properly care for them. Conditions were atrocious, to say the least.

But, that lead to a lot of research data by following the lives of kids who got adopted from those orphanages. It was determined that 4 month old was the cut-off point from where kids can still recover from traumatic experiences. Kids adopted younger than that did fine, but kids adopted after that age were affected for the rest of their lives. The fact that they didn't actually remember things consciously did not matter.
