I love the sound of all that broken glass and clashing cutlery in your kitchen!
It is artificial materials and circumstances that keep us infantile at forty!
Restricted environments are not to be confused with controlled ones. (Give a child access to your normal kitchen, but keep your bleach on top of your cupboard instead of the under the kitchen sink.) Protection is not identical to prevention (be around when your child plays, but you don't have to put it on a lead). Endorsement and encouragement is the clue, as you and I well know but how to pass it on? We do what we can: giving our own children the task to set the table with our (basic) crockery, with weight and temperature and its connection to earth which is to give them trust. One meal flows into another and this sets up a stream of trust to flow out into larger life.
