Why I'm enamored with Nico

Today, I was feeding the baby when I thought I felt or heard vibration - I don't know what sense was picking it up (perhaps Spidey sense?) but I look over at Nico and he's sitting his his Bumbo and grinning ear to ear. That's when I realized what he was doing. He had put his vibrating teething toy into the bottom of the seat, and when he sat down - VOILA! - instant butt massage! I'm pretty sure it doesn't get much cuter than that.
