Relied back to my own experiences, I had great parents, for those who didn't the story would not be the same.
And I think that this is becoming more influential now too. People are growing up with parents who are themselves spending all their time on screens - is it a good parenting example and does it inspire that feeling of wanting kids of one's own? I don't think so.
No such thing as being a perfect parent, don't anticipate a perfect child!
This is definitely an important thing to consider. I reckon a lot of people expect life to be pretty easy, pretty predictable - and it is obvious that children are neither of those things. :)
Early years in life of a child go so quickly, blink and you missed it.
Spending quality time in a family unit is far more beneficial than simply giving them all they ask for, never taking time at family meals to discuss dreams or failures. Going on picnics or laying under the stars watching the night sky.
