He's my little cousin Caio Flávio. And yes, as of now, he's about a week old. He's the son of my youngest uncle (i.e. the youngest brother of the family). His mother had a pregnancy scare and they didn't think the doctors back where they lived were gonna cut it - so mom invited them here, and they spent a few months with us until he was born.
They left yesterday, and I miss the lil' guy already.
