I had left him in the bathroom for 2 seconds, I never normally leave him in there alone at all as it's not child proofed, but I today I literally turned my back for a second and I came back to find him with a plastic cup in his hand, scooping up water from the loo and drinking it
I don't think that much actually went down his throat, but I was just struck dumb for a moment, and had no idea what to do.
He seemed fine at bedtime, the loo didn't have anything in it IYKWIM (sorry TMI) but I am still in shock at finding him doing that! He has a fascination with the loo at the moment and keeps throwing things into it, but to actually be drinking from it, eeeek.
I never usually leave any keep within his reach either but the cleaner came today and must have left them on a low shelf.
