c'est bon

Last weekend, we went to grab a quick burger at the restaurant and M had a beer.
Just for fun, we gave Mateo a sip and... for the first time in his life (although we do give him good stuff to eat) and he said : hummm, c'est bon !
M and I cracked up laughing! We couldn't believe it !

Mateo wanted more but of course, we said No!
Today, I went to the grocery store and he yelled "Bière" when we passed in front of the fridges.

Oh well...
