I have read about cases like that in children, but they didn't really chalk it up to false memory implantation. It seemed mostly to come down to children just wanting to give the answer that the authority figure wants to hear. Or what the child perceives as what they want to hear.
That still sounds like false memory implanting. They're asking detailed questions and the child knows they want them to agree, so they say yes and start believing what the question said happened. I will say that the questioner wasn't necessarily trying to get this to happen, but they still would have implanted a memory.
