Child proof latches on kitchen cabinet doors and drawers drive me crazy! I usually do not remember that the door or drawer has been child proofed with the latch and attempt to open the door only to be reminded that I have to reach in, unlatch the hook, then open the door or drawer. This three step process is not efficient, my fingers are too fat, I need two hands to open the door or drawer, I have to explain this to house guests who are trying to open kitchen drawers and I usually disrupt the contents of the drawer because I forget the door is child proofed.
Why not have a child proofing mechanism for cabinet drawers and cabinet doors that is self-releasing with multiple presses to the outside of the door or drawer rather than a latch and hook mechanism on the inside of the drawer or door. Much like self-releasing cabinets found on Yachts or boats but adjusted so that they would not open with just one press to maintain the child proof aspect.

What you are describing is a touch latch but modified in such a way that one touch will not release the catch. I can easily see developing some sort of ratcheting mechanism so that it would require several pushes on the cabinet door before the latch is released. The problem is that a small child will often engage in repetitive behavior such as repeatedly pushing on the cabinet door until it opens. The idea won't work the way it's currently described.
If it takes multiple pulls to open, it would be as annoying to use as the current designs. I would want something that could open with one motion. I think it would be best to design something that relies on the adult's advantage in strength or height. One option would be a handle mounted at the very top of the door or drawer that must be lifted up to open, similar to most modern car door handles(exterior). The spring resistance could be set high enough to make it impossible for a toddler to open while still being easy enough for an adult.
