Yep, I vote for normal too. It really is astonishing how quickly they can create astonishing mess, isn't it? I think its all just curiosity.

The other day DS got suspiciously quiet, which is always a concern, and I found him stuffing all his socks down the toilet (one of us accidently left the door open). He thought watching mummy fish them out with tongs was pretty funny and, after a while, so did I!
