We do have a plan B though if he figures out the snaps. Our friends ran into this problem with both of their kids (they would find them buck naked in their cribs in the morning). They came up with a great solution: they sewed their clothes on at night. They would stitch the zippers of their sleepers to the fabric so that they couldn't pull them down and strip. Maybe I will need to start sewing his pants to his shirt from now on! -- mam
