Another thing with the walkers is that back in the day (that you lovely spring chickens probably wouldn't remember ) is that walkers were dodgy back then - the wheel base was prone to making them unstable and they were more likely to tip them over. The ones available these days are much wider - I have seen some that wouldn't even fit through a door way. I never got one as I thought they were a giant waste of money.

Jolly jumpers I don't like either because I just don't trust that the hook will stay secure in the door jamb.

Toyboxes need to have a hydraulic safety strut on them so the lid doesn't just slam down on little fingers and closes slowly. Stupid thing is you pay upwards of $200 for a 'toybox' but you can buy a 'blanket box' for half the money without a strut - once they call it a toybox they have to have the strut and therefore it is dearer.
