First cameras: What about getting Aimee a disposal proper camera (not a toy one), which are not expensive here, about $8 including processing?, so that she can see what the intention is* when you are pointing one at her (*if you're quick enough with the processing). Let her take her own photos of Mummy and Daddy (with something recognisable in the background, like garden swing or Wendy house). It's a recovery thing once the damage has been done, so just another idea, but from what you've said, you've got a bright kid there and I'll bet she will see what's meant to be going on.
The handy tip is regarding the "kiddie locks" that you get for cupboards. They tend not to work on refrigerators because of the vacuum effect which beats the kiddie-lock every time, so the handy tip is: If you have a refigerator which has the fixings to be left- or right-hand opening, just change the handle over, but not the actual door, thus the kiddie is pulling at the hinge side to no avail, whereas adults (preferably out of sight) can simply pull the door open at the correct side.
Josh, I'm probably approaching burn-out now (aren't you glad
, but I wouldn't be surprised if others didn't have a few handy tips also...
