Mind you, kids aren’t born as a blank slate. They are born with a personality. Even before birth they have a personality, which is part genes and part other factors. Women who were pregnant more than once know this well. My parenting strategy works well for my kid and her personality. For other kids, it might be a bad idea.
For instance, Klara is extremely careful and cautious. Even when she was a baby and didn’t yet walk, she’ll crawl around, and if she found something on the floor, she would never just stuff it in her mouth, although I could see she really wanted to. She’d look at me, waiting for permission. If I said no, she might wince or grumble but she always obeyed. She even threw tantrums only after making sure her dress wouldn’t get crumpled in the process. Many children are a lot more impulsive because that’s their personality, so they need more supervision. I’m not advocating my method as a universal one. Absolutely not! Parents know their children and adapt parenting to their specific needs.
