Par la barbichette
Le premier de nous deux
qui rira
aura une tapette."
This little children's rhyme/game is a favorite. It involves grabbing onto the other person's chin (their "barbichette" = goatee) and the first person who laughs or giggles gets spanked.
So, here is a little video of the basics of raising your baby in France: grab onto that barbichette for dear life. And beyond that, photos of my bangs and Estelle and Thomas robbing my wallet.
