This reminded me of my adored -though now 'ex' - MIL
The ILs lived in the US, and we flew over for a two week stay with DD1 who had just started walking.
I was a nervous wreck on the flight out, knowing the potential for multiple disasters in a home filled with expensive china, gadgets, clocks with opening doors, and every other imaginable breakable!
We arrived to find all fragile items stored in cupboards, which had been strung together through handles to prevent opening! Even the grandfather clocks had been taped up.
MIL had left one cupboard free in both kitchen and den, and filled them with non breakable 'stuff'.
Bless her. I loved her for very good reason.
Sometimes covering up and locking away is a good thing, if it allows everyone to completely relax.
On a personal level, the only prep I do is getting the toys out of the cupboard. The dogs make more mess than the GC.
