Hi Jake, you and your nephew deserve this vacation. You working and his schooling got to be tough. So I'm leaving this thought for you. NO UNDERWEAR WHAT-SO-EVER. If he is already dressed in underwear, put him straight in diapers and remove all his underwear from his suitcase. That goes for you as well. Take lots of pics bro.Most definitely you 2 boys have a great time and drive safe bro.
Has he ever had accidents at school or at home, bedwetting maybe.
