I fully agree with this one from Blast:

Poking hole in cap of water bottle to make it spill-proof for child.

I have to do that all the time and it is not just "poke a hole" it is take the lid off and cut a straw sized hole in the lid before replacing. That is the only way I would ever give DS or DD a bottle of water to drink unless I wanted to dry out lots of stuff.
