Based on your comments about babies, I assume you don't have any.<quoted text>Does it matter if I have kids? You seem to think that making a child automatically makes you an expert. As you have demonstrated, this is not the case.
Babies don't learn in the way that adults do. You seem to think they do.
You can't learn how the raise a child by reading a book.
Try living with one for years and years and years.
Then add another one and start all over.
You tend to learn quite a bit.
And I've learned not to take child rearing advice or opinion from anyone that doesn['t have kids. They're always wrong.
