Get one of those hook things at the top of the door if it can't be fixed!

Honestly my two boys never bothered with the bathroom until about a month ago and now....well

Ollie loves getting in the loo and flicking water from it all over the place.

They knock everything off the shelves/cupboards/window sill.

Steal the toothbrushes and chew them on the landing.
And last but not least get in the sink and pull out the plug thing!

I now have to make sure it is very firmly shut at all times and if we forget within 5 mons their in there doing their mischeif.
