My granddaughter (1y 8m) uses flossers without instruction. Clearly, there is innate tooth hygiene in humans. No, what's happening is she's mimicking the adults in the house. She's observing and repeating. She's done the same thing with dolls: put them on her shoulder, pat them, make shushing noises ... because we do that with her; because she see's others do that with other babies. "Instruction"? No. But the only "innate" behaviors this child has involve eating and curiosity. Everything else is spurred by that innate curiosity.
