I've been interested to see how my parents really don't like some of the ways in which we bring up our son. They didn't like the fact that my wife breastfed for over a year. They didn't like the fact that our son slept in the same bed as us for as long as he felt like it (and he still does sometimes, even at 6).They don't like the fact that we talk to him like he's actually got his own mind and don't just discipline him.
But he's totally okay. He's well-adjusted, bright, independent, loving and is friends with everyone at his school. I'm pretty sure if we followed my parents' recipe (discipline, followed by boarding school from 8...) that he'd end up as messed up as me. I'm spending my time as a father taking the best of what I remember of my childhood and doing the other things differently.
If he ends up having children, I hope he will remember his childhood as being a happy time and bring up his kid(s) with that in mind, not trying to avoid the bad things that his parents did.
