The answer to the question "If I were a 2 year-old human, at what age would I gommage?" according to the game Clair Obscur: Expedition 33, is 17 years old. This is the age the character in the game says is correct for "gommage" in this context. However, in the game, the character actually can't count, so any answer given will be accepted for the reward.
If considering real human biology and development, this question seems metaphorical rather than literal, since "gommage" isn't a typical developmental milestone. For related real-world context, children generally lose their first baby teeth around ages 5 to 7 and finish by around 12 years old. The game appears to use the age of 17 as a midpoint of an abstract counting pattern for this question.
