emmazed jacob would/will play with his willy too. it was about this time last year it started cos dp was in afghan and i sent him an email saying, you males start playing with your favourite toy young!
its not only boys who do it though. isobel likes a rummage. 
also jacob as this thing were he says ta da, and points. it means tell me whats it called? and we have to play it about his willy every nappy change! no wonder they become obessessed with them.
jacob: ta da?
me: jacob's willy
jacob: ta da?
me: jacob's willy
jacob: ta da?
until i get the clean nappy on and fastened up!
