Does it mean what it seems to mean? That is how you tell.Let's look at it - "Once a man, twice a child" would mean that you are a child twice, and a man once - or, you are childish, then you grow up, then you grow old and become childish again.So it's not an idiom because an idiom would not make sense unless you knew exactly what it meant. It must be a proverb.
It means someone has been hurt or had something go wrong will be more carefull next time. Like if you get bitten by a dog, you will think twice before petting it again.
fool me once, shame on you. fool me twice, shame on me.
