Like many kids who come from institutional care, Sasha's first bath in our apartment in Kaz was a little rocky. Bathing isn't playtime in an orphanage, it's just time to get clean, so the kids don't have any positive associations with being stripped down and sprayed off.
It took Sasha about 2 minutes in her first bath to realize that this could be fun! And now she's a regular water bug, splashing away with anybody who happens to be in the tub with her - usually Ben, who now wears a bathing suit in the tub because he "wants to be like Ned [Flanders]." Oh well, I guess that if his role model (for bathing attire, at least) had to come from The Simpsons, Ned is a good choice.
