There's not much these boys don't like doing naked. Play the xylophone, jump up and down, eat a meal... You name it, they'll do it, and happily in the nude.
I'm sure this is probably the case with most babies. In my opinion, however, it makes everything my boys do 100x cuter!
Take a lesson from a child... do something fun naked! If you need convincing, just look at that satisfied smile!
