Déjà poo

It started with the little fella wee'ing on the bedroom floor and progressed to him leaving a giant turd on the shower floor.  Meanwhile the wee lady poo'd in the bath.  We changed the water.  She poo'd in the bath again.  We changed the water for a second time only for her to poo on her towel and follow it up with a final poo in her third bath.

What is going on with our children?
