Piper will only get in the bath if she gets to "help" give Thaddeus a bath. Which means that she can pour water on him while I soap him up. He usually has that look on his face the whole time!
He is fasinated by her. When she comes in the room he will stop whatever it as that he was chewing on and watch her! He loves when she comes and talks to him. Hopefully the love they both have for each other will last???
