What's that Saying?

What's the saying....killing two birds with one stone. Let's just say, I killed two tasks in one sink.
So, I washed the dishes, disinfected the sink, then plopped the wee one in for his eveing clean up. He loved it so much he actually threw a real tantrum when I took him out. Maybe we'll stick with the bath tub.
I must say, he is quite a little charmer.
