It’s not problematic, it’s just that none of these things were done for ‘babyproofing’
A child does not equal a baby…(going into the kitchen to get a serving piece, etc.)
I locked chemicals in my home when I was a single based on my parents’ methods. They started doing it when the youngest was already Bar Mitzvah and no grandchildren.
The fact that a baby might be safer because of these methods does not make it babyproofing.
For example, we never had gates on the stairs
