This is more of a conceptual idea for anyone to take and then go forth and conquer your own children. Sole purpose of the design was to stop my child from locking me out of the house, bathroom, his room... really any space with this style lock. However, I still wanted my toddler to be able to open the door making the standard childproof lock ineffective. I'm not claiming originality or novelty. Simply a post/guide for other parents out there to follow in case they haven't thought of a solution. I wouldn't include a design file, but Thingiverse requires it. I can't blame them; that's the point.

Also notable, I've had a 3D printer for a whopping 2 weeks. There may be better ways to do this than what I have below. But for a novice with a problem, it worked. God Speed, parents!
