Raising Zachary

One day while bathing Zachary I had him stand up so I could wash his back. Afterwards I handed him the plastic sponge thing and instructed to wash the rest of his body,"Especially you're private parts and bottom." I instructed. He dutifully washed his private parts then extended his hand toward me with the loofa-esqe wash thing and said,"You wash my bottom." "No, you can do that." I replied. He then turned his back to me, stuck his rear end out and said,"You wash my hiney! You wash my dirty, stinky butt!" and then he cracked up laughing like it was the funniest thing he'd ever heard- much less said.
